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...

background: the aim of the study is to determine the correlation between clinical and echocardiographic fi ndings and risk factors of patients with suspected acute pulmonary thromboembolism (pte) who underwent computed tomography pulmonary angiography (ctpa). materials and methods: in this cross-sectional study, 310 hospitalized patients aged >18 years with high clinical suspicion of pte referr...

We report a dual-source computed tomography study of dynamic and quantitative myocardial perfusion in a 44-year-old patient with previous documented coronary artery disease. Quantitatively, the tomography showed myocardial perfusion deficit in the territories with significant coronary stenosis, confirmed by computed tomography angiography and conventional angiography. Dual-source computed tomog...
