MR angiography (MRA) in the equilibrium phase performed with a blood pool contrast agent (BPCA) allows for visualization of the veins in addition to arterial imaging without the need of a second contrast injection. Mapping of autogenous saphenous veins as an imaging adjunct to peripheral MRA with the BPCA Gadofosveset was feasible without significant differences as compared to duplex ultrasound. It correctly allowed selection of candidates for autogenous venous graft surgery and may replace time-intensive venous ultrasound in the preoperative work-up of patients with peripheral arterial occlusive disease (PAOD).
