Diabetes and peripheral arterial occlusive disease: prospective comparison of contrast-enhanced three-dimensional MR angiography with conventional digital subtraction angiography.

摘要: OBJECTIVE. The purpose of this study was to compare contrast-enhanced three-dimensional MR angiography with conventional digital subtraction (DSA) for identifying and evaluating arteries the distal calf foot in diabetic patients severe arterial occlusive disease who will undergo bypass surgery.SUBJECTS AND METHODS. Twenty-four feet 24 consecutive diabetes limb-threatening lower extremity ischemia were prospectively imaged using an ultrafast fast low-angle shot sequence on a 1.5-T scanner. All also underwent DSA diseased within 5 days. Images interpreted randomized manner by two observers conference. Each divided into seven potential segments. Image analysis included detection patent, stenosed, or occluded vessel A vascular surgeon formulated treatment plans basis findings from then findings...
