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

1	Central Gland (CG)
2	Peripheral Zone (PZ)
