53-year-old man with the urothelial carcinoma of pT2 or more on the right side wall of the bladder.
(A) T2WI (B) fFOV DWI (C) Zoomed DWI. The bladder wall demonstrated more clearly on Zoomed DWI than on fFOV DWI. An artifact appears from the intestine and the rectum in both images of fFOV and Zoomed DWI. VI-RADS score was 5 for both readers.

Fig 3.
70-year-old man with the urothelial carcinoma of pTa on the right lateral to posterior wall of the bladder.
(A) T2WI (B) fFOV DWI (C) Zoomed DWI. The tumor appeared as the lesion without tumor stalk in fFOV DWI, and VI-RADS score was 3 for both readers. In contrast, the tumor appeared as a papillary lesion with tumor stalk in Zoomed DWI, and VI-RADS score was 2 for both readers.
Fig 4.
61-year-old woman with the urothelial carcinoma of pTa on the posterior wall of the bladder.
(A) T2WI (B) fFOV DWI (C) Zoomed DWI. VI-RADS score was 3 for reader 1 and 2 for reader 2 with fFOV DWI. In contrast, the tumor stalk clearly appeared on Zoomed DWI, and VI-RADS score was 2 for both readers.
Fig 5.
83-year-old woman with the urothelial carcinoma of pT1 on the left lateral wall of the bladder.
(A) T2WI (B) fFOV DWI (C) Zoomed DWI. The tumor appeared as a papillary lesion with tumor stalk in both fFOV and Zoomed DWI, and VI-RADS score was 2 for both series.
Fig 6.
66-year-old man with the urothelial carcinoma of pT2 on the anterior wall of the bladder.
(A) T2WI (B) fFOV DWI (C) Zoomed DWI. The tumor appeared as a lesion without stalk in both fFOV and Zoomed DWI, and score of VI-RADS was 3 for both fFOV and Zoomed DWI series.
