Abstract:
Background: Wrist joint damage is early, common symptom and in diagnostic criteria of rheumatoid arthritis. Objective: to describe characteristics of MRI of the wrist in rheumatoid arthritis. Subjects and methods: This was a describe study. The study included 41 patients who were diagnosed rheumatoid arthritis according to the criteria of American College of Rheumatology- 1987 from January to October - 2006. Results: The average disease duration was 16.4 \xb114.71months. According to Rheumatoid Arthritis Magnetic Resonance Imaging Score (RAMRIS) 2002, damages on MRI included: 100% of patients had synovitis (5.9 \xb1 2.20), 100% of patients had bone erosions (15.3 \xb1 11.06) and 90% of patients had bone edema (7.3 \xb1 5.86), total score 28.6 \xb1 16.58. The correlative coefficient between synovitis and bone edema: r=0.43, P<0.01, between synovitis and bone erosions:r=0.61, P<0.01, between bone erosions and bone edema: r=0.55, P<0.01. MRI revealed bone erosions in 100% of patients having rheumatoid arthritis less six months after symptom onset compared with 0% of patients on radiography. In patients with over 2 years of disease duration, this rate on MRI was 100% of patients compared with 87.5% of patients on radiography. Conclusions: The specific damages of the wrist on MRI have value in diagnosis of early rheumatoid arthritis. \r\n', u'\r\n', u'\r\n', u'
