📌 Rheumatoid Arthritis

✅ Early Identification and Quantification of Synovitis

• MR imaging helps in the early detection and quantification of synovitis, a key predictor for future erosions in rheumatoid arthritis.

 

✅ Synovial Proliferation

• Synovial proliferation in rheumatoid arthritis appears as a mass-like tissue prominence within the joint capsule on MR imaging. 
• It shows low signal on T1-weighted images and hyperintense on T2-weighted or STIR sequences.

 

✅ Bone Edema and Erosion Prediction

• Bone edema often accompanies synovitis and is found in subchondral bone. 
• In the hands and wrists, its presence is the strongest predictor of future erosions.
