Figure 14b. (a) Coronal three-dimensional fast gradient-echo dynamic contrast-enhanced MR angiogram (6/1.3, 45° flip angle) and (b) coronal single-shot fast spin-echo MR urogram (2,047/620, 10-cm section thickness) in a healthy renal donor. Note the excellent demonstration of the main renal arteries bilaterally. The renal veins and inferior vena cava (arrow in a) are also well shown. On the urogram, the collecting systems and ureters, as well as a distended urinary bladder, are well shown.
