How well can you rate bone age?

The automatic rating of BoneXpert is more accurate than a manual rating. To illustrate this, we have created an app that will assess your accuracy in manual bone age rating on ten childrens’ hand x-ray images. Your ratings are compared to the average of 46 Dutch radiologists, a reference which is close to the true rating.

Bone Age Rating Test


(We give acknowledgments to Bram van Ginneken, professor at Radboud UMC, who proposed to set up this test as a cunning way of illustrating the power of computerised bone age rating. The test was originally made for the Hands-on AI day in Nijmegen in 2018, where we acquired the ratings of 46 Dutch radiologists – so our acknowledgements go to them as well.)
