1 From the Department of Diagnostic and Interventional Radiology, University Hospital Essen, Hufelandstrasse 55, 45122 Essen, Germany (M.G., H.H.Q., J.F.D., M.E.L., J.B., C.U.H., S.B., H.K., S.G.R.); and Siemens Medical Systems, Erlangen, Germany (M.S.). Received August 8, 2001; revision requested September 28; revision received November 5; accepted January 7, 2002. Address correspondence to M.G. (e-mail: mathias.goyen@uni-essen.de).
A technique for performing whole-body magnetic resonance (MR) angiography with multistation three-dimensional MR angiography by using a self-developed rolling table platform that integrates the surface coil was evaluated in three volunteers and 10 patients. Use of the surface coil resulted in high signal-to-noise and contrast-to-noise ratios, which translated into sensitivity and specificity of 95.3% and 95.2%, respectively, for detection of significant stenoses (luminal narrowing, >50%) in lower extremity peripheral vascular disease.
