Despite the increased sensitivity of other modalities (particularly MRI), radiography remains the mainstay of imaging in the diagnosis and follow-up of RA. It's possible to see in this case:
- joint space narrowing: symmetrical or concentric
- marginal erosions: due to erosion by pannus of the bony “bare areas”
Similar to the hands, there is a predilection for the DIP and MTP joints.
