Abstract:
Objective To assess the diagnostic value of MR imaging of the wrist synovitis in early rheumatoid arthritis.Methods 60 wrists in 30 patients underwent MR imaging examination,including T1WI,T2WI,STIR and contrast-enhanced fat-suppressed 3D fast-gradient-echo sequence.MRI manifestations were analysed in comparison with clinical and laboratory test data.Results All changes including synovial hyperplasia and pannus formation(30 cases),articular cartilage destruction(21 cases),bone erosion(16 cases),joint effusion(25 cases) and tendon lesion of wrists could be showed clearly by MRI.The signal intensity of the pannus before and after administration of contrast agent and the enhanced curve of the pannus could be used to assess the lesions whether or not activation.Conclusion MRI is helpful in diagnosing early rheumatoid arthritis.
