The Cancer Imaging Program of the National Cancer Institute (NCI) in collaboration with the International Society for Biomedical Imaging (ISBI) will launch a grand challenge in segmentation of internal structures of the prostate gland based on magnetic resonance imaging data. The challenge will take place at the ISBI Symposium which takes place April 7-11, 2013 in San Francisco, CA. A full list of challenges taking place at the ISBI Symposium can be found at

Challenge Structure and Data Availability

The overall goal of this challenge is to promote the development of robust open and closed source codes that can automatically identify the peripheral zone and the central gland from volumetric T2-weighted MR image sets. Data for the prostate challenge has been provided by Boston University and Radboud University, Nijmegen Medical Centre (the Netherlands). The challenge data has been divided into three groups:

  1. Training cases have been made publicly available to all interested participants. This consists of 60 subjects, half of which taken from the Prostate-Diagnosis collection (1.5T) and the other half from the Prostate-3T collection (3T). Ground truth data for each subject will also be provided in the form of NRRD image segmentations created by expert observers.
  2. Leader Board cases will be made available closer to the date of the conference. Participants in the contest will be able to submit their segmentation results for evaluation using this data set. This will consist of 5 additional cases from both the Prostate-Diagnosis collection (1.5T) and the Prostate-3T collection (3T). NRRD segmentations used for generating participant scores will be held by the contest organizers.
  3. The 2013 ISBI Grand Challenges will be held on the last day of the conference (Thursday, April 11th). Testing data will be made available to participants at this time, which will again consist of 5 additional cases from both the Prostate-Diagnosis collection (1.5T) and the Prostate-3T collection (3T).
