BACKGROUND Transcatheter aortic valve replacement (TAVR) is a novel technique developed in the last decade to treat severe aortic stenosis in patients who are non-surgical candidates because of multiple comorbidities. METHODS Since the technique is performed using a transvascular approach, pre-procedural assessment of the aortic valve apparatus, ascending(More)
Sixteen-slice multidetector CT findings of a pulsatile pseudoaneurysm of the mitral-aortic intervalvular fibrosa, in a woman following aortic valve replacement, are presented. Multidetector CT depicted the pseudoaneurysm and enabled dynamic evaluation of its lumen through the cardiac cycle, documenting expansion during systole and almost complete collapse(More)
PURPOSE To prospectively compare subjective radiological quality, radiation dose and effect on workflow using digital radiography (DR) vs. conventional screen film (SF) radiography in the Small Bowel Follow-Through (SBFT) examination. METHODS Five attending and four resident radiologists compared hard-copy images from 11 SBFT examinations, for which every(More)
C ardiac imaging is of special value in the diagnosis and management of hypertrophic obstructive cardiomyopa-thy. 1 Echocardiography 2 and magnetic resonance imaging, 3 in particular, have been used to diagnose the disorder, to elucidate its pathophysiology, and to guide and document the results of treatment. 4 A 41-year-old woman was evaluated for(More)
Recent advances in multi-detector CT (MDCT) are turning it into one of the leading technologies for detection of coronary artery disease. We propose here an automatic coronary stenosis detection mechanism that uses computerized tomography coronary angiography (CTCA) images extracted from the MDCT data. The artery is first isolated using image morphology and(More)
