Gadolinium magnetic angioresonance in the study of aortoiliac disease.

There is a need for noninvasive methods for the early identification of patients with intermittent claudication who need surgical treatment. Newer magnetic resonance angiography (MRA) techniques allow detailed study of the arterial tree with image quality similar to that of conventional arteriography. From April 1997 to January 2001, 30 patients with intermittent claudication of the lower limbs were studied with both imaging methods.
