A 69-year-old man with hematuria for 2 months. A biopsy revealed high-grade urothelial carcinoma. The patient underwent 2 cycles of neoadjuvant chemotherapy followed by transurethral resection of the bladder tumor. A Axial T2-weighted image shows an exophytic tumor on the right side of bladder, < 1 cm in greatest dimension. Disruption of low-signal-intensity muscularis propria is unclear. B Axial diffusion-weighted image (b = 1000) and (C) apparent diffusion coefficient images show uninterrupted intermediate signal-intensity muscularis propria. D Axial contrast-enhanced image shows uninterrupted low-signal-intensity muscularis propria. The final VI-RADS score was 1 for all readers. Histopathology confirmed a non-muscle-invasive bladder cancer
