摘要:

AbstractTo better understand the use of magnetic resonance angiography (MRA) in evaluating peripheral vascular disease, the authors studied arteries in the foot and ankle. Twenty patients with arterial occlusive disease of the lower extremity were studied with two‐dimensional time‐of‐flight MRA, and the results were compared with those of 10 conventional x‐ray arteriograms, four digital subtraction arteriograms, and three intraoperative arteriograms. The studies were reviewed and rated by three radiologists blinded to the patients' clinical history. Also, the first 16 patients were examined with MRA before and after intravenous injection of gadopentetate dimeglumine. The mean confidence levels for the reviewers' interpretations of the MRA studies were significantly higher than those for the conventional arteriograms for the medial plantar, lateral plantar, and plantar arch arteries of the feet (P≦ 0.005).Postcontrast MRA images were inferior to precontrast images because of overlapping of veins and arteries. Time‐of‐flight MRA without gadolinium can serve as a useful complementary study for evaluating patients with peripheral vascular disease in the f
