¹ From the Departments of Diagnostic and Interventional Radiology (M.G., C.U.H., T.C.L., J.F.D., S.G.R.) and Angiology (K.K.), University Hospital Essen, Hufelandstrasse 55, 45122 Essen, Germany.

View larger version (84K): [in a new window]   Figure 1. Images obtained in a 67-year-old man with a history of PVD who could walk a distance of less than 200 m without pain. Left: Intraarterial anteroposterior DSA image. Middle: Whole-body 3D fast low-angle shot coronal MR angiogram (2.1/0.7; flip angle, 25°; partitions, 40 interpolated by zero filling to 64; slab thickness, 120 mm; section thickness, 3.0 mm interpolated to 1.9 mm; FOV, 390 x 390 mm; matrix, 256 x 225 interpolated by zero filling to 512 x 512; acquisition time, 12 seconds per station) obtained with the rolling table platform. The DSA image and 3D MR angiogram show diffuse atherosclerotic disease of the peripheral vasculature. Right: Whole-body 3D fast low-angle shot coronal MR angiogram obtained with the same parameters as were used to obtain the middle image depicts a high-grade stenosis of the left subclavian artery (lower arrow) and of the left internal carotid artery (upper arrow). The lesions were initially unsuspected.

Whole-body 3D fast low-angle shot coronal MR angiogram (2.1/0.7; flip angle, 25°; partitions, 40 interpolated by zero filling to 64; slab thickness, 120 mm; section thickness, 3.0 mm interpolated to 1.9 mm; FOV, 390 x 390 mm; matrix, 256 x 225 interpolated by zero filling to 512 x 512; acquisition time, 12 seconds per station) obtained in a 63-year-old man with PVD. Because of the extended FOV, the image revealed an infrarenal AAA with a maximum diameter of 5.3 cm, which was clinically not suspected.
