Sonographic features more specific to malignancy include a nonparallel orientation, an echogenic halo, posterior acoustic enhancement, and associated microcalcification.
Purpose: The purpose of this study is to determine the left ventricular mass (LVM) and the left coronary artery dimension and to investigate the relationship between the two values in the normotensive group and hypertensive group with using 16-channel multidetector CT (MDCT). Materials and Methods: Among the patients who underwent a CT coronary angiogram procedure using 16-channel MDCT at Ajou University Hospital from October 2004 to February 2005, 33 patients became the subjects of this study. These 33 patients showed normal findings without calcification or stenosis of the coronary arteries. The total volume of the left ventricular wall was calculated using work-in-progress cardiac CT reconstruction software. The LVM could then be directly calculated by multiplying the left ventricular muscle volume by the myocardial tissue density, which was assumed to be 1.05 g/cm 3
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
