Abstract

To detect a renal artery stenosis and assess its hemodynamic and functional significance in five breath holds. In a single MR exam. T1 weighted FLASHand T2 weighted fast spin echo techniques are used to assess renal morphology, multiphase 3D gadolinium (Gd) MRA to evaluate the renal arteries, and a segmented EPI cine phase-contrast technique to measure renal artery bloodnow, A standardized image analysis is performed to assess kidney size, cortico-medullar differentiation (CMD), parenchymal enhancement, the degree ofrenal artery stenosis, abnormalities in blood now pattern, and any associated abdominal vascular disease. Multiphase 3D-Gd-MRA accurately assesses atherosclerotic renal artery disease particularly in the presence of an associated aortic aneurysm. Delayed parenchymal enhancement, loss of CMD, and decrease in kidney size can be detected. In combination with decreased systolic velocity components, the diagnosis of a hemodynamically and functionallysignificant stenosis can be made. High-resolution single-phase 3D-Gd-MRA is preferable for evaluation of fibromuscular dysplasia or hypoplastic vessels. The combination of different breath hold techniques in a single, standardized MR exam allows to detect the hemodynamic and functional significanceof a renal artery stenosis, (C) 1999 Wiley-Liss, Inc.
