Background: The risk of developing pulmonary embolism (PE) is high in patients infected with COVID-19, and its diagnosis a severe challenge for healthcare professionals duringthe COVID-19 pandemic. Physicians are frequently usingcomputed tomography angiography(CTPA), d-dimer, well score the PE. Methods: A retrospective study was used which we investigated reliability clinical scores by collecti...

Introduction: Capnography, is an easy, fast and practical method which its application in the diagnosis of Pulmonary Thromboendarterectomy (PTE) has recently been studied. This study aimed to assess the diagnostic value of end-tidal CO2 (ETCO2) and the alveolar dead space (AVDS) in the diagnosis of patients suspected to PTE who have been referred to the emergency department. Materials and Metho...

PURPOSE In this study, we aimed to document imaging practices and diagnostic strategies used by emergency physicians in patients with suspected high-probability pulmonary embolism (PE). MATERIALS AND METHODS A questionnaire investigating the diagnostic strategies used by the emergency physicians in the evaluation of venous thromboembolism was mailed electronically to all emergency department ...

BACKGROUND Diagnosis of pulmonary thromboembolism (PTE) in dogs relies on computed tomography pulmonary angiography (CTPA), but detailed interpretation of CTPA images is demanding for the radiologist and only large vessels may be evaluated. New approaches for better detection of smaller thrombi include dual energy computed tomography (DECT) as well as computer assisted diagnosis (CAD) technique...

In emergency departments, suspected pulmonary embolism (PE) can be safely ruled out by a normal multi-slice CT angiography (CTPA) [1–4] without the need for additional leg compression ultrasonography (CUS). This diagnostic approach for those who develop symptoms of PE during hospitalization has been validated by only a limited number of studies. [2,5]. In this study we aim to estimate prevalenc...

BACKGROUND Pulmonary embolism (PE) is a relatively common and potentially life threatening clinical condition with estimated prevalence to be 0.4%. Early diagnosis of PE followed by adequate treatment reduces the risk of major complications. Multislice computed tomography pulmonary angiography (CTPA) currently constitutes an imaging modality of choice in patients with suspicion of PE. Computed ...

BACKGROUND AND PURPOSE Invasive cerebral DSA has largely been replaced by CTA, which is noninvasive but has a compromised arterial view due to superimposed bone and veins. The purpose of this study was to evaluate whether arterial visualization in CTPa is superior to standard CTA, which would eliminate the need for an additional CTA scan to assess arterial diseases and therefore reduce radiatio...
