Figure 19b. Peripheral arterial disease in a 65-year-old man with ischemic symptoms in the left leg. (a) Coronal MIP image from contrast-enhanced MR angiography of the thigh station shows diffuse disease of both superficial femoral arteries with a totally occluded left popliteal artery (arrow). (b) Coronal image from contrast-enhanced MR angiography performed with dedicated calf injection shows the occluded popliteal artery (large arrow) with a reconstituted posterior tibial artery (small arrows) and significantly diseased peroneal and anterior tibial arteries. (c) Coronal MIP image from TOF imaging of the same calf shows that the distal posterior tibial artery is widely patent (large arrows) and the anterior tibial artery is diminutive (small arrows). (d) Coronal TOF image of the left foot shows a patent plantar arch (small arrows) supplied by the posterior tibial artery (large arrow). The dorsalis pedis artery is absent.
