Aortic and lower-extremity arterial disease: evaluation with MR angiography versus conventional angiography.

摘要: PURPOSE: To compare magnetic resonance (MR) angiography with conventional in evaluation of the aorta and lower-extremity arterial system. MATERIALS AND METHODS: Fifty-seven patients were evaluated femoral MR angiography. Iliac artery segments two-dimensional contrast material-enhanced three-dimensional time-of-flight Infrainguinal regions a dedicated coil. Arteries depicted on images separately interpreted as 20 anatomic segments. Disease classification included normal to moderate disease (0%-50% stenosis), severe stenosis (> 50% diffuse (more than one occlusion. Four readers rendered treatment recommendations. RESULTS: Substantial almost perfect interobserver agreement (kappa, 0.66-1.00) was achieved most cases for angiogram interpretation. The three ex...
