Mapping of hepatic vascular anatomy: dynamic contrast-enhanced parallel MR imaging compared with 64 detector row CT Heilmaier C; Sutter R; Lutz AM; Seifert B; Weishaupt D; Marincek B; Willmann JKRadiology 2007[Dec]; 245 (3): 872-80The study was approved by the institutional review board, and informed consent was obtained from all patients. The purpose of this study was to retrospectively evaluate the feasibility, reliability, and accuracy of breath-hold dynamic contrast material-enhanced parallel gradient-echo (GRE) magnetic resonance (MR) imaging for mapping the hepatic vascular anatomy, with contrast-enhanced 64-detector row computed tomography (CT) as the reference standard. The parallel GRE MR data sets of 100 patients acquired at 1.5 T were evaluated independently by two blinded readers with respect to (a) image quality for depiction of the hepatic arteries and the portal and hepatic veins and (b) presence of arterial stenosis and variant hepatic vasculature. The readers rated image quality to be good or excellent for 91.1%-100% of the vessels. At parallel GRE MR imaging, the readers diagnosed variant hepatic vessels and arterial stenosis with 94%-100% accuracy. They concluded that parallel GRE MR imaging, as compared with 64-detector row CT, is feasible for hepatic vascular mapping and enables reliable and accurate detection of variant hepatic vasculature and diagnosis of arterial stenosis.
