For each magnetic resonance imaging feature, frequencies of definite and severe manifestation are indicated as a percentage. -, not present. Joint effusion, bone marrow edema and erosions could be determined in 38 hands from our 26 patients. Synovitis could only be assessed in 31 hands, due to lack of venous access for the application of contrast agent. |
