Three-station ‘bolus-chase’ moving-table lower limb MR angiograms. Left study (a) in a diabetic patient with calf claudication shows preserved aortoiliac and femoropopliteal segments but typical occlusive below-knee tibial disease. Middle study (b) in bilateral claudicant with absent right femoral pulse shows occluded right common and external iliac arteries with reasonably preserved infra-inguinal run-off on that side, whereas on the left while the iliac arteries are reasonable there is stenotic femoral artery disease in the proximal thigh. Right study (c) in a claudicant patient with impaired left femoral pulse reveals shelf-like lower aortic stenosis, stenotic left iliac disease and an occluded right superficial femoral artery but preserved infrapopliteal run-off. Note that in these non-critical claudicant patients there is little ‘venous contamination’, and these MRA images are as presented immediately after acquisition with automated MIP post-processing and stitching to give an instant overview vascular map of multilevel disease
