RSNA Pediatric Bone Age Challenge (2017)

As part of its efforts to spur the creation of artificial intelligence (AI) tools for radiology, in 2017 RSNA conducted a challenge to assess bone age from pediatric hand radiographs, a routine task that determines an important developmental indicator.

About the 2017 RSNA Pediatric Bone Age Challenge

The 2017 RSNA AI data challenge used a dataset developed by Stanford University and the University of Colorado and was annotated by multiple expert observers.

Over 250 participants, including AI developers, data scientists, radiologists and other medical specialists, competed in the challenge. Participants worked in 37 teams to submit the outcomes of their algorithms. Teams with the most accurate predictions were recognized at RSNA 2017.
