Figure 5a. Contrast-enhanced MR angiography of the lower extremity performed with the hybrid method. Imaging of the calf was performed first with 20 mL of gadolinium contrast material, and MIP images of each side were produced separately to prevent superimposition on the lateral projections. After the calf study, imaging of the pelvis and thigh was performed with 40 mL of gadolinium contrast material and the moving-table technique (from the pelvis to the thigh). Coronal MIP images show the arteries of the pelvis (a), thigh (b), right calf (c), and left calf (d). Note the short segmental occlusion of the right superficial femoral artery with reconstitution (arrows in b) and the high origin of the right posterior tibial artery (arrowhead in c).
