Pulmonary sequestration is a rare congenital malformation that is uncommonly diagnosed during adulthood. Pulmonary sequestrations can manifest with variable presentations. It can remain asymptomatic or present with more severe symptoms such as hemoptysis and recurrent pneumonia. Diagnosis can be confirmed with computed tomography angiogram or angiography. Treatment with embolization of the affe...

Although the frequency of haemoptysis in Eisenmenger’s syndrome is well recognised, the high prevalence of pulmonary artery thrombus has been newly appreciated through the growing use of non-invasive imaging. Three patients with Eisenmenger’s syndrome with haemoptysis are reported who underwent computed tomography pulmonary angiography and cardiovascular magnetic resonance. Each patient was fou...

OBJECTIVE The aim of this study was to prospectively test the performance and potential for clinical integration of software that automatically calculates the right-to-left ventricular (RV/LV) diameter ratio from computed tomography pulmonary angiography images. METHODS Using 115 computed tomography pulmonary angiography images that were positive for acute pulmonary embolism, we prospectively...

OBJECTIVE The purpose of this study was to evaluate the effectiveness of contrast-enhanced ultrasound with a second-generation contrast agent in distinguishing between occlusion and pseudo-occlusion of the cervical internal carotid artery, comparing it with that of conventional Doppler ultrasound and the gold standard, computed tomography angiography. METHOD Between June 2006 and June 2012, w...

patients and methods we evaluated radiation exposure from initial and downstream testing in a prospectively collected, matched cohort evaluated for cp in the emergency department (ed) with either ccta compared with usual care over a median follow-up of 19.6 months. effective radiation dose was calculated using published conversion factors. results prospective, ecg-triggered acquisition using a ...

azygos vein aneurysm is a rare cause of a posterior or paratracheal mediastinal mass. trauma or conditions causing elevated flow or pressure in the azygos system, such as cardiac failure or cirrhosis of the liver are secondary causes of aneurysm of the azygos vein. we report a case of asymptomatic saccular aneurysm of the azygos vein in a 45-year-old man with blunt minor chest trauma. the azygos...

background: the celiac axis, superior mesenteric artery (sma), and hepatic artery are the most important branches of abdominal aorta due to their vascularization field. the aim of our study was to evaluate the prevalence of different anatomical variation of celiac axis, sma, hepatic artery, and its branches with multidetector computed tomography (mdct) angiography of upper abdomen arteries. mat...

A case of an asymptomatic 32-year-old male with a complex congenital pulmonary vein varix is reported herein. Chest X-ray incidentally revealed a tubular opacity passing from the periphery of the left lingula to the mediastinum. ECG gated multidetector computed tomography showed the opacity to be a vessel emptying into the left atrium via the left superior pulmonary vein. In addition, a second ...
