Abstract

Objective To study the RA (rheumatoid arthritis) in patients with MRI signal differences in the sequence. Methods Retrospective analysis of our hospital from 2008 September to 2014 May, clinical data of 73 patients with RA in our department examination as the study group, and 65 cases of healthy volunteers were selected in the control group the same time period, the study group patients with parietal axial scans were performed comparing the signal difference. Results the study group patients with dynamic enhanced MRI, tendon, joint capsule synovial pannus, compared with the control group, both showed thickening performance (P<0.05),and the sequence of MRI signal were different (P<0.05). Conclusion Dynamic enhanced MRI implementation of RA patients, the synovial membrane thickness, Slopemax, ERmax, TIC and other indicators, combined with early MRI features, can clear the pathological changes, and different sequence of MRI signal, has the features and characteristics of RA, the early diagnosis, treatment, prognosis and so on, have a very important clinical value, should be combined with the specific circumstances of patients, given the promotion.
