Conclusion
We develop an AI approach for automatic scoring joint space narrowing and bone erosion. Through semantic segmentation of the joint space region as well as integration of multilevel interconnection across joints and damage types, our method achieved high prediction accuracy in quantifying joint space narrowing, approaching the clinical upper limit of this problem.
