A case demonstrating the use of bp-MRI for determining various scores. A patient over 85 years old with hematuria underwent mp-MRI prior to the initial TURBT. T2WI revealed two sessile tumors without a high signal intensity thickened inner layer on the right bladder wall, with no clear disruption of the low signal intensity muscularis propria observed. Tumors with clear stalks were observed on DWI and ADC (Arrow). Based on bp-MRI, all readers assigned a T2WI category of 3 and a DWI category of 2. However, no clear tumor with stalk was visible on DCE. The final VI-RADS score was determined to be 3. The T stage after TURBT was T1-high grade. A: T2WI; B: DWI; C: ADC; D: DCE. bp-MRI: biparametric magnetic resonance imaging; mp-MRI: multiparametric magnetic resonance imaging; TURBT: transurethral resection of bladder tumor; T2WI: T2-weighted images; DWI: diffusion-weighted imaging; ADC: apparent diffusion coefficient; DCE: dynamic contrast-enhanced; VI-RADS: Vesical Imaging-Reporting and Data System
