The purpose of this study is to develop a new contrast-free MR angiography technique without using any ECG triggering for the vascular assessment of lower extremities in patients with diabetes. Healthy volunteers and diabetes underwent both MR angiography and skeletal muscle perfusion imaging at rest and during an isometric contraction exercise. The angiography, perfusion, and even possible calcification of vessels can be assessed in one imaging session in patients with diabetes.
