SPIE, along with the support of the American Association of Physicists in Medicine (AAPM) and the National Cancer Institute (NCI), will conduct a “Grand Challenge” on quantitative image analysis methods for the diagnostic classification of clinically significant prostate lesions.  As part of the 2017 SPIE Medical Imaging Symposium, the PROSTATEx Challenge will provide a unique opportunity for participants to compare their algorithms with those of others from academia, industry, and government in a structured, direct way using the same data sets.  For more details, go to  To register for the challenge visit

For more information:

The database for this challenge will contain a total of approximately 350 MRI cases, each from a single examination from a distinct patient.  Approximately 60% of the cases will serve as the training set, and the remaining 40% of the cases will serve as the test set, with each case consisting of four sets of MRI scan data: two sets of T2-weighted images (transaxial and sagittal; DICOM format), Ktrans images (computed from dynamic contrast-enhanced (DCE) images; mhd format), and apparent diffusion coefficient (ADC) images (computed from diffusion-weighted (DWI) imaging; DICOM format).  Each case will contain at least one prostate lesion with biopsy-proven malignancy status or with imaging findings with sufficiently low suspicion of clinical significance.  Lesion location (along with a reference thumbnail image of the lesion) will be provided as this is not a detection task.  Gleason scores and PI-RADS scores will not be released with this challenge, since they will become the focus of a follow-up challenge to be held in conjunction with the 2017 AAPM Annual Meeting in July 2017.
