PROSTATEx-2 Challenge 2017

PROSTATEx2

SPIE-AAPM-NCI Prostate MR Gleason Grade Group Challenge
(Conducted in conjunction with the 2017 AAPM Annual Meeting; PROSTATEx-2 is the second part of the PROSTATEx Challenge that was part of SPIE MI 2017)

The American Association of Physicists in Medicine (AAPM), along with SPIE (the international society for optics and photonics), and the National Cancer Institute (NCI), will conduct a part 2 “Grand Challenge” on the development of quantitative multi-parametric magnetic resonance imaging (MRI) biomarkers for the determination of Gleason Grade Group in prostate cancer.

As part of the 2017 AAPM Annual Meeting, the PROSTATEx-2 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. 

A session at the 2017 AAPM Annual Meeting will focus on the PROSTATEx-2 Challenge; the two top-performing participants will receive a waiver of the meeting registration fee in order to present their methods during this session. Challenge participants are encouraged to submit their work for peer review to the AAPM’s scientific journal Medical Physics.

To participate in the PROSTATEx-2 Challenge
, please go the Challenge website. Participation in the PROSTATEx-2 Challenge acknowledges the educational, friendly competition, and community-building nature of this challenge and commits to conduct consistent with this spirit for the advancement of the medical imaging research community. 



The truth associated with the test set cases is expected to be made publicly available after publication of the PROSTATEx-2 Challenge and its predecessor PROSTATEx Challenge www.spie.org/PROSTATEx

See the SPIE Digital Library/Medical Imaging Article for a discussion of lessons learned from the 2015 LUNGx Challenge, also sponsored by SPIE, AAPM, and NCI.
