Figure 1a. Bilateral claudication in a 67-year-old man. (a) DSA image and (b) coronal three-dimensional Gd-BOPTA-enhanced MR angiogram (4.4/1.2) show stenoses of the right common (arrowhead) and external iliac arteries, irregularities of the superficial femoral and popliteal arteries, and stenosis at the level of the right trifurcation. Greater than 50% stenoses (arrows) are seen at the level of the superficial femoral and popliteal arteries on the left. There is good correlation between the MR angiography and DSA findings. All stenotic lesions were correctly diagnosed at MR angiography.

Figure 2a. Severe left-sided claudication in a 65-year-old man. (a) DSA and (b) coronal three-dimensional Gd-DOTA-enhanced MR angiographic MIP images (4.4/1.2) show stenosis of the left common iliac artery (arrow). There is good correlation between the MR angiography and DSA findings. In b, thin-slab MIP reconstructions without subtraction were obtained at the level of the distal run-off vessels; this facilitated the elimination of overlying fat signal.

Figure 3a. Stenoses in a 79-year-old diabetic woman with an ulcer on the right foot. (a) DSA and (b) coronal Gd-BOPTA-enhanced MR angiographic MIP images (4.4/1.2) of the right leg show stenoses of the popliteal artery (thick arrow), anterotibial artery (arrowheads), and tibiofibular trunk (thin arrow). The MR angiographic MIP image findings (b) confirmed all stenotic lesions, as well as the occluded posterotibial artery, seen in a.
