Biparametric 3 T prostate MR of one patient at Charité Berlin, the T2, ADC and DWI as one three-channel image on the T2's grid, with the transitional and peripheral zones drawn by a radiologist (Prostate158, test split).

- Image. T2, ADC and the high-b DWI as one image of three components a voxel, all on the T2's grid, onto which the provider resampled the ADC and DWI: 0.40 to 0.50 mm pixels, 3 to 3.15 mm between slices, 23 to 29 slices around the gland. Values as delivered, no unit. No mask.
- Labels. The zone map of the first reader on the T2: 1 the transitional zone, the gland outside the peripheral zone (its central zone included), as MSD_Prostate's label 2; 2 the peripheral zone, a posterior crescent. The tumour masks are not used.
- Truth. Radiologists drew the zones on every study; the test studies have a second reader, whose zone map agrees with the first at a median Dice of 0.867 (0.800 to 0.928) on the transitional zone and 0.770 (0.589 to 0.841) on the peripheral zone (the deposit's interrater.csv): the room above that is small. The corpus scores against the first reader, as on the training studies.
- Tolerance. The surface Dice is at 4 mm, as in MSD_Prostate.
- Start. A mask of the whole image scores a Dice of 0.065 on the transitional zone and 0.032 on the peripheral zone at the median of the test cases, an Otsu mask on the T2 0.033 and 0.044. TotalSegmentator 2.18.0's total_mr prostate overlaps the union of the two zones at a Dice of 0.333 on case 001 and 0.804 on 002, and has no zones.
- Overlap. The 158 studies are of Charité Berlin; the corpus's other prostate MR (PICAI, PROSTATEx_Seg, ProstateISBI2013, PROMISE12, MSD_Prostate, QINProstateRepeat) come from Radboud, Boston, Haukeland, University College London and other centres, none from Charité, so no patient is shared. No image was compared.

About the data
- Test cases
- The provider's 19 test studies, the whole test split. 13 development studies drawn with seed 2026 from the 139 training studies.
- Truth
- contours by experts the deposit's zone map of its first reader on the T2: 1 the transitional zone, which the provider takes as the gland outside the peripheral zone, 2 the peripheral zone; drawn by radiologists, a second reader on the test studies only (Adams et al. 2022)
