# NCI-ISBI 2013 — Automated Segmentation of Prostate Structures

T2-weighted MRI dataset for prostate zonal segmentation (Peripheral Zone and Central Gland).

## Dataset Details

| Field | Value |
|---|---|
| Modality | T2-weighted MRI (1.5T + 3T) |
| Body part | Prostate |
| Classes | 2 — Peripheral Zone (PZ), Central Gland (CG) |
| Subjects | 80 (60 train / 10 leaderboard / 10 test) |
| Format | DICOM images + NRRD segmentations |
| License | CC BY 3.0 |

## Structure

```
images/
Training/ # 60 cases (30 Prostate3T + 30 ProstateDx)
Leaderboard/ # 10 cases
Test/ # 10 cases
segmentations/
Training/ # 60 NRRD masks
Leaderboard/ # 10 NRRD masks
Test/ # 10 NRRD masks
```

Each patient directory under `images/` contains DICOM slices (~15-38 per case).
Segmentation masks are NRRD files with matching patient IDs.

- **Prostate3T-\***: acquired at 3T (Siemens TIM, surface coil)
- **ProstateDx-\***: acquired at 1.5T (Philips Achieva, endorectal coil)

## Segmentation Labels

| Label | Structure |
|---|---|
| 0 | Background |
| 1 | Central Gland (CG) |
| 2 | Peripheral Zone (PZ) |
