On CXR, the finding of hilar vascular prominence with an abrupt absence of distal vessels is known as the Westermark sign (as seen in the CXR of our patient). Sreenivasan S, Bennett S, Parfitt VJ. In multivariate analysis, obesity, cigarette smoking, and hypertension were independent predictors of pulmonary embolism. Any study which compared CT pulmonary angiography to an acceptable reference standard or prospectively followed up a cohort of patients with a normal CT pulmonary angiogram was included. Pulmonary Embolism. Counterintuitively, thrombolysis did not reduce mortality or recurrent PE at 90 days. In this case, the Westermark sign is evident in the right upper lung zones. 2002 Mar. This study determines the rate of negative chest radiography results in patients found to have disease and the potential contribution of negative findings to a diagnosis discordant with heart failure by an emergency physician. (2010) ISBN:1605479764. The percentage of subsegmental emboli among patients with acute PE was 15.6%. Although radiologists are responsible for the final reading of chest radiographs, very often the clinicians, and in particular the emergency physicians, are alone in the emergency room facing this task. CTPA-proven pulmonary embolus (not shown). The pooled false negative rate of combined negative CT pulmonary angiography and negative deep vein thrombosis testing was 1.5% (95% CI 1.0 to 1.9%). Postgrad Med 2014; 90: 420-421. It is one of several described signs of pulmonary embolus on chest radiographs. The chest radiograph was interpreted as normal in only 18% of patients with acute PE. Diagnostic studies give conflicting results for the diagnostic accuracy of CT pulmonary angiography. Presentación de 1 caso. The study included 200 chronic hypoxemic patients divided into 2 groups, the group I consisting of 42 women and 58 men and the group II consisting of 48 women and 52 men. Cardiomegaly is the most common chest radiographic abnormality associated with acute pulmonary embolism. Check for errors and try again. ... Rajendran R, Singh B, Bhat P. Subtle CXR signs of PE: The pala's and Westermark … We suggest that physicians to be aware of and utilize CXR findings such as Palla's sign, Westermark sign and Hamptons hump to help with the diagnosis of PE and to exclude other conditions that can mimic venous thrombo-embolism. Cardiomegaly is the most common chest radiographic abnormality associated with acute pulmonary embolism. Images in cardiovascular medicine. Most thrombi are generated in the deep venous system of the lower leg and pelvis. Fleischer FG. J Emerg Trauma Shock Palla's sign and Hamptom Hump in PE. Heavy cigarette smokers also had an increased risk of primary pulmonary embolism. The following is a summary of the recommendations and good practice points for the BTS Guideline for the initial outpatient management of pulmonary embolism. Nils Johan Hugo Westermark (1892 - 1980) was a Swedish radiologist. Pulmonary embolism has an untreated mortality of about 30% and is the commonest cause of death after elective surgery (accounting for up to 15% of all post-operative deaths).2 w2 It is the commonest cause of maternal death in the United Kingdom.3 The descending interlobar branch of the right pulmonary artery is enlarged, causing a "sausage" appearance towards … All rights reserved. The theory behind the sign is either obstruction of the pulmonary artery or distal vasoconstriction in hypoxic lung 3. cases of idiopathic pulmonary fibrosis on HRCT were investigated. In one study (PIOPED) this sign was present on ~10% of chest x-rays of patients with confirmed pulmonary embolus 2.Â. Many parenchymal, vascular, and other ancillary findings may be observed on both imaging modalities with a highly detailed depiction of abnormalities on multislice CT. A comprehensive review of chest radiograph findings is presented with side-by-side correlations of CT images reformatted mainly in the frontal plane. Westermark sign: ( west'er-mark ), in chest radiography, decreased lung markings from oligemia caused by pulmonary embolism. The literature on this uncommon benign lesion is reviewed. This study are realised in the order to answer the question: How well the chest X ray reflect the cardiac dysfunction? Westermark sign is a focal peripheral hyperlucency secondary to oligemia, and is a sign of pulmonary embolus on … Major pulmonary embolism: review of a pathophysiologic approach to the golden hour of hemodynamically significant pulmonary embolism. Computed tomographic (CT) pulmonary angiography is becoming the standard of care at many institutions for the evaluation of patients with suspected pulmonary embolism. Paradoxical embolism in the presence of a patent foramen ovale (PFO) is a rare but well-known entity and should always be looked for in case of a PE associated with systemic thromboembolism. Circulation. Recognition of enlargement of the descending pulmonary artery may increase suspicion of pulmonary embolism; in particular, detection of "sausage" appearance of the vessel should identify patients with high probability of disease.

BACKGROUND: Idiopathic Pulmonary Fibrosis is a chronic pulmonary disorder characterized by thickening of Smaller clots travel more distally, infarcting the lung and causing pleuritic pain. Patients lacking signs of congestion on ED chest radiography were more likely to have an ED non-heart failure diagnosis than patients with signs of congestion. Chest radiographs were interpreted to show cardiac enlargement for 149 of 309 patients with right ventricular hypokinesis that was detected by echocardiography (sensitivity, 0.48) and for 178 of 485 patients without right ventricular hypokinesis (specificity, 0.63). Hypertension, even after adjustment for body mass index, was also associated with an increased risk of primary pulmonary embolism (RR=1.9; 95% CI, 1.2-2.8). Acta Observation of the radiologic changes in pulmonary embolism. The case was discussed and a literature review was made. Although chest radiography is quick and inexpensive, previous research suggests that it is often misleading in emergency department (ED) patients with decompensated heart failure, resulting in misdiagnosis and inappropriate treatment. Osborn A, Blaser S, Salzman K. Encyclopedia of Diagnostic Imaging. Few studies recruited unselected emergency department patients. The diagnostic quality of CTPA was insufficient in 5.9%, acceptable in 8.2%, and excellent in 85.9% of the patients. In acute pulmonary embolism that manifests as complete arterial occlusion, the affected artery may be enlarged. D-dimer should be measured by the quantitative rapid enzyme-linked immunosorbent assay (ELISA), and the combination of a negative D-dimer with a low or moderate clinical probability can safely exclude pulmonary embolism in many patients. 1, 64-MDCT Pulmonary Angiography and CT Venography in the Diagnosis of Thromboembolic Disease, Chest radiographic findings in patients with acute pulmonary embolism: observations from the PIOPED Study, A prospective study of risk factors in pulmonary embolism in women, Chest Radiographs in acute pulmonary embolism. These prospective data indicate that obesity, cigarette smoking, and hypertension are associated with increased risk of pulmonary embolism in women. Neither pulmonary artery enlargement nor cardiomegaly appears sensitive or specific for the echocardiographic finding of right ventricular hypokinesis, an important predictor of mortality associated with acute pulmonary embolism. Pulmonary embolism often is undetected during life, even though adequate diagnostic procedures are available, probably because the condition is not suspected. (2007) ISBN:B0011ZYZR2. The clinical gestalt of experienced clinicians and the clinical prediction rules used by physicians of varying experience have shown similar accuracy in discriminating among patients who have a low, moderate, or high pretest probability of pulmonary embolism. The percentages of nondiagnostic examinations for CTPA and CTV were 5.2% and 10.8%, respectively. had positive finding on chest X ray. A prospective observational study at 52 hospitals in seven countries. The PIOPED II investigators recommend stratification of all patients with suspected pulmonary embolism according to an objective clinical probability assessment. Transbronchial biopsy was performed and the final diagnosis was alveolar pulmonary microlithiasis. Venous stasis is increased by immobility and dehydration, which leads to the accumulation of clotting factors and platelets. Radiographic feature of PE: Hamptom's Hump. X-rays can be used for this purpose. Pulmonary embolism (PE) is a serious clinical entity carrying significant morbidity and mortality. {"url":"/signup-modal-props.json?lang=us\u0026email="}. Acute PE and acute DVT were observed in 25.2% and 18.0%, respectively. Westermark signs. Westermark sign (1938) of relative oligemia on CXR in pulmonary embolism Gary Zhang; March 15, 2020; CXR eponyms in pulmonary embolism . Risk factors for pulmonary embolism are divided into major and minor factors. Fleischner lectured and published extensively on pulmonary embolus and pulmonary hypertension between 1941 and 1962. Radiol 1938;19:357‑72. J Appl Physiol 1965; 16: 141-147. Box 1 CXR appearance of Westermark and Palla signs Westermark sign: regional pulmonary oligaemia Palla sign: enlargement of the descending pulmonary artery Figure 1 (A) Westermark sign (white arrow) and Palla sign (black arrow) demonstrated on plain film chest radiograph. Acute pulmonary embolism may occur rapidly and unpredictably and may be difficult to diagnose. The results of chest radiographs were abnormal for 509 of 655 patients (78%) who had undergone a major surgical procedure within 2 months of the diagnosis of pulmonary embolism: normal results for chest radiograph often accompanied pulmonary embolism after genitourinary procedures (37%), orthopedic surgery (29%), or gynecologic surgery (28%), whereas they rarely accompanied pulmonary emboli associated with thoracic procedures (4%). This feature did not occur in patients with unconfirmed suspicion of pulmonary embolism. Westermark sign is a focal peripheral hyperlucency secondary to oligemia, and is a sign of pulmonary embolus on chest radiographs. On examination, the patient was in respiratory distress and haemodynamic … DISCUSSION: Plain film evidence of Westermark sign is not often seen. Three reviewers independently scanned titles and abstracts for inclusion of studies. Studies varied in prevalence of pulmonary embolism (19-79%), patient groups, and method quality. The radiologist needs to determine the quality of a CT pulmonary angiographic study and whether pulmonary embolism is present. 2. In about one-fourth of the patients with pulmonary embolism, enlargement and shape modification were so marked that the artery showed a special "sausage" appearance. Chest radiographs were interpreted to show pulmonary artery enlargement for 118 of 309 patients with right ventricular hypokinesis (sensitivity, 0.38) and for 117 of 483 patients without right ventricular hypokinesis (specificity, 0.76). In ICOPER, two thirds of the patients with massive PE did not receive thrombolysis or embolectomy. MATERIALS. CTPA-proven pulmonary embolus (not shown). Factors that cause misdiagnosis of pulmonary embolism may be patient related, technical, anatomic, or pathologic. Multislice spiral CT is becoming an increasingly important tool for diagnosing pulmonary embolism. Treatment can reduce mortality, and appropriate primary prophylaxis is usually effective. suggestive of Hampton’s hump. Westermark sign is a focal peripheral hyperlucency secondary to oligaemia, and is a sign of pulmonary embolus on chest radiographs. Hampton hump refers to a dome-shaped, pleural-based opacification in the lung most commonly due to pulmonary embolism and lung infarction (it can also result from other causes of pulmonary infarction (e.g. (2010), differential diagnoses of airspace opacification, presence of non-lepidic patterns such as acinar, papillary, solid, or micropapillary, myofibroblastic stroma associated with invasive tumor cells. To appraise the evidence on the diagnostic accuracy of CT pulmonary angiography and the prognostic value of a negative CT pulmonary angiogram in the diagnosis of pulmonary embolism. Se le realizó biopsia transbronquial y el diagnóstico definitivo fue una microlitiasis alveolar pulmonar. Chest radiographs of 1,063 patients with suspected PE were reviewed. embolism. Chest X-Ray Based Tumor Growth Assessment for Lung Tumor Diagnosis. The most common chest radiographic interpretations were cardiac enlargement (27%), normal (24%), pleural effusion (23%), elevated hemidiaphragm (20%), pulmonary artery enlargement (19%), atelectasis (18%), and parenchymal pulmonary infiltrates (17%). & METH ODS: X-rays of 30 diagnosed Fleischner Sign 2.0 (1958). Patel UB, Ward TJ, Kadoch MA. Westermark was also an accomplished sailor and won a silver medal, as a member of the Swedish team, at the 1912 Olympics in Stockholm 7. Material and methods. On the Roentgen Diagnosis of Lung Embolism, Interobserver Reliability of the Chest Radiograph in Pulmonary Embolism, Management of Massive and Submassive Pulmonary Embolism, Iliofemoral Deep Vein Thrombosis, and Chronic Thromboembolic Pulmonary Hypertension A Scientific Statement From the American Heart Association, Pulmonary CT Angiography in Patients Suspected of Having Pulmonary Embolism: Case Finding or Screening Procedure? Up to 50% of leg thrombi embolise; clots above the knee do so more commonly than clots below the knee.4 w3 Large clots may lodge at the bifurcation of the main pulmonary arteries, causing haemodynamic compromise. ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. Clinicians should not rule out heart failure in patients with no radiographic signs of congestion. Moreover, the sensitivity of CXR is much impaired when the study is performed at bedside by portable machines, particularly in the diagnosis of some important causes of acute dyspnoea, such as pulmonary embolism, pneumothorax, and pulmonary edema. Westermark sign (1938) of relative oligemia on CXR in pulmonary embolism Gary Zhang; March 4, 2020; Pulmonary Embolism: Next Generation . We found that the overall interobserver agreement was good for the exclusion of any pleural or parenchymal abnormality (k = 0.6; 95% CI: 0.56-0.64) but fair (k = 0.28; 95% CI: 0.17-0.40) between junior radiologists when evaluating supine chest radiographs. Westermark’s sign: is distension of pulmonary vasculature proximal to embolism with loss of vascular markings distally, i.e. The aim of this prospective, originally designed, clinical - diagnostic study including 200 chronic hypoxemic patients was to assess the possibility of implementation of noninvasive diagnostic strategy and to investigate the incidence of pulmonary embolism and parameters of diagnostic accuracy of radiological findings according to Shintz criteria, echocardiography, lung perfusion scanning according to PIOPED criteria. Clinics in diagnostic imaging : Right lower lobe segmental pulmonary embolus. Hampton's hump, also called Hampton hump, is a radiologic sign which consists of a shallow wedge-shaped opacity in the periphery of the lung with its base against the pleural surface. If the quality of the study is poor, the radiologist should identify which pulmonary arteries have been rendered indeterminate and whether additional imaging is necessary. The patient was diagnosed with pulmonary embolism (PE) and treated with heparin and edoxaban. Se discutió el caso y se revisó, Join ResearchGate to discover and stay up-to-date with the latest research from leading experts in, Access scientific knowledge from anywhere. In pregnant women, ventilation/perfusion scans are recommended by many as the first imaging test following D-dimer and perhaps venous ultrasound. The importance of this causal link is under debate as most travellers who develop venous thromboembolism have additional risk factors.8 A 2001 study of 135.29 million passengers showed an incidence of pulmonary embolism of 1.5 cases per million for travel over 5000 km, compared with 0.01 cases per …. Palla sign: Enlarged right descending pulmonary artery Brenes-Salazar JA. Out of 200 hypoxemic patients, 49 patients (24.5%) were found to have pulmonary embolism. A 47-year-old woman presented to the … Westermark sign is a sign of pulmonary embolus seen on chest radiographs. Risk stratification and appropriate consideration of diagnostic strategies alternative to pulmonary CT angiography, as the first-line and stand-alone technique, should guide clinical decision making in patients who are suspected of having pulmonary embolism. The D-dimer level was This finding is uncommon in patients with PE but has high specificity, Subtle CXR signs of PE: The pala's and Westermark signs. Partial filling defects due to acute pulmonary embolism are often centrally located, but when eccentrically located they form acute angles with the vessel wall. Roentgenologically, in addition to the classical infarct, we look … acute unilateral airspace opacification (differential), acute bilateral airspace opacification (differential), acute airspace opacification with lymphadenopathy (differential), chronic unilateral airspace opacification (differential), chronic bilateral airspace opacification (differential), osteophyte induced adjacent pulmonary atelectasis and fibrosis, pediatric chest x-ray in the exam setting, normal chest x-ray appearance of the diaphragm, posterior tracheal stripe/tracheo-esophageal stripe, obliteration of the retrosternal airspace, leflunomide-induced acute interstitial pneumonia, fibrotic non-specific interstitial pneumonia, cellular non-specific interstitial pneumonia, respiratory bronchiolitis–associated interstitial lung disease, diagnostic HRCT criteria for UIP pattern - ATS/ERS/JRS/ALAT (2011), diagnostic HRCT criteria for UIP pattern - Fleischner society guideline (2018)​, domestically acquired particulate lung disease, lepidic predominant adenocarcinoma (formerly non-mucinous BAC), micropapillary predominant adenocarcinoma, invasive mucinous adenocarcinoma (formerly mucinous BAC), lung cancer associated with cystic airspaces, primary sarcomatoid carcinoma of the lung, large cell neuroendocrine cell carcinoma of the lung, squamous cell carcinoma in situ (CIS) of lung, minimally invasive adenocarcinoma of the lung, diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH), calcifying fibrous pseudotumor of the lung, IASLC (International Association for the Study of Lung Cancer) 8th edition (current), IASLC (International Association for the Study of Lung Cancer) 7th edition (superseeded), 1996 AJCC-UICC Regional Lymph Node Classification for Lung Cancer Staging, focal peripheral hyperlucency secondary to oligemia resulting in a collapsed appearance of vessels distal to the occlusion, central pulmonary vessels may also be dilated. relief of his symptoms. Right pulmonary artery is not dilated in post stenotic dilatation of pulmonary artery and idiopathic dilatation of pulmonary artery. Westermark sign (1938) Westermark sign describes chest x-ray findings in pulmonary embolism of a clarified area distal to a large vessel that is occluded by an embolus. Anant Subramanian Krishnan, M.D., and Tristan Barrett, M.D. ... An area of focal oligemia due to embolic obstruction of a large pulmonary branch is known as Westermark’s sign. ### “Economy class syndrome” Study methods were appraised independently by two researchers, and data were extracted independently by three researchers. Pulmonary embolism (PE) is the obstruction of one or more pulmonary arteries by solid, liquid, or gaseous masses. chronic PE: still valid in the current CT era. Thus, knowing and understanding some of the more specific CXR signs can be useful. Lippincott Williams & Wilkins. Chest . air travel ten days earlier. Recent studies in hospital in-patients with a wide variety of acute medical illnesses have shown a risk of venous thromboembolism comparable with that seen after major general surgery.5 create excessive radiation burden on patient. Wonders of Radiology. Early recognition of these findings on plain radiography can help facilitate early intervention, which is critical in cases of central pulmonary emboli. The Two chest physicians reviewed the chest radiographs obtained during that hospitalization. Thus, knowing and understanding some of the more specific CXR signs can be useful. We compared initial ED admitting diagnosis to the criterion standard of a hospital discharge diagnosis of heart failure and related these to radiographic findings of heart failure (interstitial edema, pulmonary edema, or vascular congestion, as determined by a staff radiologist) for patients first treated in the ED. Overall, there were 1619770 person-years of follow-up. However, it is unclear whether recently developed clinical prediction rules, using explicit features of clinical examination, are comparable with clinicians' gestalt. Nurses' Health Study with 16 years of follow-up from 1976 to 1992. Eponymythology associated with chest X-ray signs in pulmonary embolus and pulmonary infarction. Acute massive pulmonary embolism (PE) carries an exceptionally high mortality rate. Unable to process the form. A clinical gestalt strategy was used in 7 studies, and in the low, moderate, and high pretest categories, the rates of pulmonary embolism ranged from 8% to 19%, 26% to 47%, and 46% to 91%, respectively. AMIRSYS. Roughly ten percent of pulmonary embolisms result in pulmonary infarction, but many patients die of PE without being diagnosed. Post Grad Med 2013; 89: 241-242. Despite the publication of evidence-based clinical practice guidelines to aid in the management of VTE in its acute and chronic forms, the clinician is frequently confronted with manifestations of VTE for which data are sparse and optimal management is unclear. Z. V. Maizlin. Please refer to the full guideline for full information about each section. The relative risk (RR) of primary pulmonary embolism was 1.9 (95% CI, 0.9-3.7) for women currently smoking 25 to 34 cigarettes per day and 3.3 (95% CI, 1.7-6.5) for those smoking 35 cigarettes or more daily as compared with never smokers. To characterize chest radiographic interpretations in a large population of patients who have received a diagnosis of acute pulmonary embolism and to estimate the sensitivity and specificity of chest radiographic abnormalities for right ventricular hypokinesis that has been diagnosed by echocardiography. Percutaneous needle biopsy revealed it to be a sclerosing haemangioma which was subsequently removed by a left lower lobectomy. As in MDCT scanning with a smaller number of slices, the combination of CTV with CTPA in 64-MDCT results in a small but definitive increase in the percentage of patients with a diagnosis of thromboembolic disease. The level of interobserver agreement for the interpretation of the chest radiograph as consistent or not with PE was fair (k = 0.24; 95% CI: 0.19-0.29), regardless of the observer experience. The focal area of increased translucency (oligaemia), occurs due to impaired vascularisation of the lung from primary mechanical obstruction or reflex vasoconstriction. localized peripheral oligemia (rare) 7. The purpose of our study was to investigate whether CT venography (CTV) performed after CT pulmonary angiography (CTPA) using 64-MDCT provides additional findings in the diagnosis of thromboembolic disease. CONCLUSION: 90% of the patients had positive x-ray finding. Prospective study based on biennial, mailed questionnaires. Westermark’s sign is distal oligaemia in the of sudden onset. This study was conducted to determine the chest radiographic presentation in known cases of acute PE presenting to a tertiary care hospital. Chest X-ray exam showed intraparenchimatous calcification in the lungs. The annual incidence is 60-70 per 100 0001 w1; it is a common cause of breathlessness and pleuritic pain. In particular, the optimal use of advanced therapies for acute VTE, including thrombolysis and catheter-based therapies, remains uncertain. Experienced clinicians' gestalt is useful in estimating the pretest probability for pulmonary embolism and is complementary to diagnostic testing, such as lung scanning. The proportion of patients with a non-heart failure ED diagnosis and the diagnostic sensitivity of radiographic findings of heart failure are calculated. collapsed lung, consistent with lung infarction. Pulmonary vessels on CXR. [Medline] . Although chest radiographs are essential in the investigation of suspected PE, their main value is to exclude diagnoses that clinically mimic PE and to aid in the interpretation of the ventilation-perfusion scan. Pregnancy-adapted YEARS algorithm provides high certainty in ruling out pulmonary embolism and high efficiency in reducing the need for CTPA http://bit.ly/2GgH4sv. QJM; WEstermark's and Palla's signs in acute and chronic PE: still valid in the current CT era. Journal of thoracic imaging. Radiographic feature of PE: Thoracic Imaging. If pulmonary embolism is not excluded, contrast-enhanced computed tomographic pulmonary angiography (CT angiography) in combination with venous phase imaging (CT venography), is recommended by most PIOPED II investigators, although CT angiography plus clinical assessment is an option. The sign results from a combination of: the dilation of the pulmonary arteries proximal to the embolus and It is one of several described signs of pulmonary embolus on chest radiographs. We advocate the use of a clinical prediction rule because it has shown to be accurate and can be used by less-experienced clinicians. 1. A group of 112822 women aged 30 to 55 years in 1976, free from diagnosed cardiovascular disease or cancer at baseline. This report addresses the management of massive and submassive pulmonary embolism (PE), iliofemoral deep vein thrombosis (IFDVT),and chronic thromboembolic pulmonary hypertension (CTEPH). Follow up scans are needed during long treatment procedure which Observation of the radiologic changes in pulmonary PE was confirmed angiographically in 383 patients and excluded in 680 patients. Clinically, it is a difficult condition to diagnose and remains under treated condition in Pakistan due to non-availability of objective tests and lack of awareness among physicians. Thus X-Ray Westermark Sign in Pulmonary Embolism List of authors. This is confirmed by CT angiography of the chest, which shows large clot burden obstructing the right pulmonary artery. WEstermark's and Palla's signs in acute and There were 85,376 patients with chest radiograph results and an ED admitting diagnosis. Hamptom's Hump. 1. As a result, he has been eponymously affiliated with other CXR changes often observed in pulmonary embolism such as the raised hemidiaphragm with basal atelectasis. In the emergency setting, thoracic imaging by standard chest X-ray (CXR) plays a crucial role in the diagnostic process, because it is of fast execution and relatively not expensive. Overall, there were 15,937 patients with no signs of congestion on ED chest radiography, giving a negative rate of 18.7% (95% confidence interval [CI] 18.4% to 18.9%). patient was started on heparin injection with significant CXR C.T/MRI V/Q scanPlasma D dimers. A pulmonary embolism is an obstruction of part of the pulmonary vascular tree, usually caused by a thrombus that has travelled from a distant site—for example, the deep veins in the leg. Venous thromboembolism (VTE) is responsible for the hospitalization of >250 000 Americans annually and represents a significant risk for morbidity and mortality. Based on self-report and medical records, we documented 280 cases of pulmonary embolism, of which 125 were primary (no identified antecedent cancer, trauma, surgery, or immobilization). was not seen in a previous study done three months ago, Conventional chest radiography remains the cornerstone of day to day management of the critically ill occasionally supplemented by computed tomography or ultrasound for specific indications. This study was sought to evaluate the interobserver agreement for interpreting the chest radiograph of patients with suspected acute pulmonary embolism (PE). The primary source is thrombus from the deep veins of the legs. To determine the sensitivity, specificity, and positive and negative predictive values of chest radiographic findings in patients suspected of having acute pulmonary embolism (PE). In most cases, the embolism is caused by … Causes of dyspnoea are various and involve not only cardiovascular and respiratory systems. Nils Johan Hugo Westermark (1892 - 1980) was a Swedish radiologist. In the group I of 100 patients (42 women and 58 men) with chronic hypoxemia and secondary erythrocytosis the diagnosis of pulmonary embolism was confirmed in 39%, that being statistically significantly different (p.
