Arterial stenosis of the lower extremities is the most common cause of amputation in diabetic patients. Contrast-enhanced MR angiographyis images suffer from venous contamination and is reported potential renal toxicity. Our NCE-MRA showed a high percentage of stenosis segments and provides higher image quality than the CE-MRA. The NCE-MRA technique is capable of clear depiction and accurate detection of the whole lower extremity arterial tree in patients with diabetes.
