Figure 7. Transitional cell carcinoma of the midureter in a 68-year-old man. (a) Coronal maximum intensity projection (MIP) and (b) source images from excretory MR urography demonstrate a large mass inside the midureter (arrows) with proximal ureteral and pelvocalyceal dilatation. (c) The axial standard T2 weighted turbo spin echo (TSE) sequence confirms the diagnosis by demonstrating a soft-tissue mass (arrowhead) with heterogeneous signal intensity.
