Background and Aim: Pulmonary thromboembolism is an important clinical problem in the patients after major surgeries and is often difficult to diagnose because of nonspecific clinical symptoms. Diagnosis of pulmonary embolism is based on medical imaging methods. The aim of this study was to evaluate the results of CT pulmonary angiographies of the patients with primary clinical diagnosis of pul...

RATIONALE Clinical probability assessment is a fundamental step in the diagnosis of pulmonary embolism. OBJECTIVES To develop a predictive model for pulmonary embolism based on clinical symptoms, signs, and the interpretation of the electrocardiogram. METHODS The model was developed from a database of 1,100 patients with suspected pulmonary embolism, of whom 440 had the disease confirmed by...

INTRODUCTION Acute pulmonary embolism has varied presentations ranging from asymptomatic, incidentally discovered emboli to massive embolism, causing immediate death. Tumor embolism is a rare but unique complication of malignancies. This uncommon catastrophe of a malignant tumor in a young patient, culminating as a pulmonary embolism, is being reported for the first time. CASE PRESENTATION A ...

    Background: Since pulmonary angiography is the only non-invasive method for diagnosing pulmonary embolism, the use of radiation reduction methods without affecting the quality of images seems necessary. One of the simplest reasons for unnecessarily increasing of patient exposure is repetitive imaging due to poor image quality. Therefore, it is necessary to identify and ...

the lack of pathognomonic signs and symptoms makes the diagnosis of pulmonary embolism (pe) difficult. here, we report a case of a 42-year-old man presented to the emergency department with worsening epigastric pain, hypotension, frank bradycardia, and final diagnosis of pe. although previous studies have indicated that abdominal pain was observed in 6.7% of patients with pe, the exact reason f...

Spiral CT-Angiography (CTA) is increasingly used for the diagnosis of pulmonary embolism. However, radiologists must view more than 50 images in order to detect thrombi in the arteries and distinguish them from artifacts caused by partial volume, heart motion, etc. In this study, we present a new method for automated segmentation of the pulmonary vascular tree in spiral CTA data sets for 3D vis...

Introduction: Pulmonary embolism (PE) is a common lethal disease that its clinical symptoms may be seen in many other diseases. Computed tomography pulmonary angiography (CTPA) is a valuable diagnostic modality for detection of PE. In addition, it can accurately detect the other diseases with clinical symptoms similar to PE. The aim of this study is to evaluate the frequency of PE and nonemboli...

introduction antiphospholipid syndrome (aps) associated with intra-cardiac thrombus and pulmonary embolism is infrequent. however, the presence of pleural effusion is extremely rare. case presentation a 42-year-old woman, admitted with palpitation, dyspnea and history of stroke and thrombocytopenia is described. doppler sonography revealed deep vein thrombosis. moreover, subsequent investigatio...
