Automatic Segmentation of the Left Ventricle in Cardiac CT Angiography Using Convolutional Neural Network [PDF]
arXiv, 2017 Accurate delineation of the left ventricle (LV) is an important step in evaluation of cardiac function. In this paper, we present an automatic method for segmentation of the LV in cardiac CT angiography (CCTA) scans. Segmentation is performed in two stages.

Comparison of Fractional Flow Reserve and Myocardial Perfusion Imaging in Saphenous Vein Grafts
Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Revascularization decision‐making for saphenous vein grafts (SVGs) relies on angiographic lesion severity estimation, as studies on fractional flow reserve (FFR) for detecting ischemia in SVGs are scarce. Aims To compare FFR and quantitative coronary angiography (QCA) of SVGs against myocardial perfusion imaging (MPI) and to ...

Effects of theophyline on contrast [PDF]
Journal of Mazandaran University of Medical Sciences, 2006 Background and purpose: Contrast-induced nephropathy (CN) is one of the most common causes of iatrogenic acute renal failure. In fact CN is the third leading cause of new ARF in hospitalized patients. Radiocontrast-associated ARF is a significant problem

Incidence and 1‐Year Prognostic of Unstable Angina After High‐Sensitivity Troponin Assessment
Catheterization and Cardiovascular Interventions, EarlyView.ABSTRACT Background Incidence and prognostic of unstable angina after high‐sensitivity troponin assesment is controversial. Aims This study evaluated prognostic of a contemporary population of patients with UA defined using high sensitive T troponin (T hs‐cTn) measurements and with significant coronary artery disease (CAD). Methods Consecutive patients
