Optimal Monochromatic Energy Levels in Spectral CT Pulmonary Angiography for the Evaluation of Pulmonary Embolism
BACKGROUND The aim of this study was to determine the optimal monochromatic spectral CT pulmonary angiography (sCTPA) levels to obtain the highest image quality and diagnostic confidence for pulmonary embolism detection. METHODS The Institutional Review Board of the Shanghai Jiao Tong University School of Medicine approved this study, and written informed consent was obtained from all partici...
متن کاملOveruse 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 کاملEvaluation of CT angiography findings in the patients with clinical diagnosis of pulmonary thromboembolism
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...
متن کاملEvaluation of the confounding factors disturbing the quality of CT images of pulmonary angiography
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 ...
