Abstract
IntroductionMagnetic resonance imaging (MRI) was used to study the hand and wrist in very early rheumatoid arthritis (RA), and the results were compared with early and established disease.MethodsFifty-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.ResultsEdema, 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.ConclusionsEdema, 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.
Highlights
Magnetic resonance imaging (MRI) was used to study the hand and wrist in very early rheumatoid arthritis (RA), and the results were compared with early and established disease
Erosions, and synovitis were present in all groups of RA (Table 2)
Analysis of variance demonstrated that the three groups were significantly different for bone edema and erosions
Summary
Magnetic resonance imaging (MRI) was used to study the hand and wrist in very early rheumatoid arthritis (RA), and the results were compared with early and established disease. Rheumatoid arthritis (RA) is a chronic systemic inflammatory disease characterized by prominent joint manifestations. The presence of marginal erosions, seen on conventional radiographs of the hand and wrist, has been viewed as a specific and relatively sensitive diagnostic finding [2]. Erosions, and synovitis have been detected by magnetic resonance imaging (MRI) in patients with disease duration of < 1 year [3,4,8,9,10,11,12,13,14,15].
