Overuse and underuse of pulmonary CT angiography in patients with suspected pulmonary embolism
Background: The aim of the present study was to evaluate the utilization and diagnostic yields of CT pulmonary angiography (CTPA) using the Revised Geneva score and Wells’ criteria, in patients with suspected pulmonary embolism (PE). Methods: One hundred and twelve adult patients underwent CTPA for suspected PE were participated in this study. The outcome was positive or neg...
متن کامل[Pulmonary CT angiography in pulmonary embolism: beyond diagnosis].
c Right ventricular dysfunction (RVD) is the most common cause of short-term mortality in patients with acute pulmonary embolism (PE).1 Shock and hemodynamic instability, defined as systolic blood pressure below 90mmHg or a fall of more than 40mmHg, is a clinical marker of high risk and identifies patients who may benefit from early thrombolysis.2 However, in PE patients without hemodynamic com...
متن کاملPulmonary rhabdomyosarcoma complicated with pulmonary artery extensive embolism
Rhabdomyosarcoma (RMS) is an uncommon type of soft-tissue malignancy which mainly influences children. Primary pulmonary RMS (PPR) is extremely uncommon. Here, we describe a case of PPR complicated by pulmonary artery extensive embolism. A 41-year-old Chinese woman characterized of repeating cough complained of chest congestion. Despite first diagnosis of pulmonary infection, antibiotic therapy...
متن کاملAutomated Segmentation of the Pulmonary Vascular Tree in Spiral CT Angiography for Computerized Detection of Pulmonary Embolism
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...
متن کاملUtilization of CT Pulmonary Angiography in Suspected Pulmonary Embolism in a Major Urban Emergency Department
Objectives. We conducted a study to answer 3 questions: (1) is CT pulmonary angiography (CTPA) overutilized in suspected pulmonary embolism (PE)? (2) What alternative diagnoses are provided by CTPA? (3) Can CTPA be used to evaluate right ventricular dilatation (RVD)? Methods. We retrospectively reviewed the clinical information of 231 consecutive emergency department patients who underwent CTPA...
