Figure 3: (a–i) (A–C T2-weighted images, D–F diffusion-weighted imaging and G–I apparent diffusion coefficient maps). Multiple fungating urinary bladder mass lesions are seen with restricted diffusion. The lesions do not invade the dark T2 signal wall of the urinary bladder (yellow arrow). The mean apparent diffusion coefficient values of the bladder lesions measure 1.34×10−3 mm2/s, 1.31×10−3 mm2/s, 1.27×10−3 mm2/s, and 1.1×10−3 mm2/s. The lesions are pathologically proved as multicenteric bladder urothelial carcinoma (grade I).
