Figure 5d. Example of an MR angiographic study with no visible motion in the region of the segmental renal arteries in a 78-year-old man. (a) Anteroposterior digital subtraction angiogram shows severe proximal main renal arterial stenoses (curved arrows in a-d) bilaterally, which are well depicted on the (b) coronal maximum intensity projection image of the high-spatial-resolution small-FOV MR angiogram. The segmental renal arteries are also well depicted on both the (c) anteroposterior selective digital subtraction angiogram of the left main renal artery and (d) magnified coronal maximum intensity projection image of the high-spatial-resolution small-FOV MR angiogram. A left accessory renal artery (straight arrows in a, b, and d) is also well depicted. Pulse sequence parameters are as summarized in Table 1. PRE = preangioplasty image.
