Methods Fifty-seven patients fulfilling the new American College of Rheumatology criteria for RA 26 with very early RA VERA 18 with early RA ERA and 13 with established RA ESTRA disease duration 3 months 12 months and 12 months respectively were enrolled in the study. MRI of the dominant hand and wrist was performed by using fat-suppressed T2-weighted and plain and contrast-enhanced T1-weighted sequences. Evaluation of bone marrow edema synovitis and bone erosions was performed with the OMERACT RA MRI scoring system. Results Edema erosions and synovitis were present in VERA and the prevalence was 100 96.15 and 92.3 respectively. Significant differences in edema and erosions were found between VERA and ESTRA P 0.05 . No significant difference was found in synovitis. Conclusions Edema erosions and synovitis are findings of very early RA. MRI by detecting these lesions may play an important role in the management of these patients. Introduction Rheumatoid arthritis RA is a chronic systemic inflammatory disease characterized by prominent joint manifestations. Inflammation of the synovial membrane leads to the formation of a highly cellular inflammatory tissue the pannus which by eroding cartilage and bone leads to joint destruction and ankylosis 1 . Articular involvement of the hand and wrist has been considered a very frequent presenting finding 1 . The presence of marginal erosions seen on conventional radiographs of the hand and wrist has .
