Abdomen, Pelvis, and Extremities: Diagnostic Accuracy of Dynamic Contrast-enhanced Turbo MR Angiography Compared with Conventional Angiography—Initial Experience

Abstract

To determine the value of contrast material-enhanced three-dimensional turbo magnetic resonance (MR) angiography compared with conventional cut-film or digital subtraction angiography for evaluating arterial stenosis in the abdomen, pelvis, and extremities. For detection of significant stenosis, MR angiography had 91% sensitivity and 89% specificity. This technique is highly sensitive in lesion detection, but stenosis tended to be overestimated.
