OBJECTIVE: To study the ability of low-cost low-field dedicated extremity magnetic resonance imaging (E-MRI) to assess and predict @entity16 in the wrist and metacarpophalangeal (MCP) joints of @entity1 with early @entity309 . METHODS: 24 previously untreated @entity1 with @entity309 with joint symptoms for <1 year were evaluated at the time of diagnosis and after 6 and 12 months of @entity1499 treatment with conventional clinical or biochemical examinations, x rays of both hands and wrists, and E-MRI of the dominant wrist and @entity2720 . RESULTS: At baseline, all @entity1 showed magnetic resonance imaging (MRI) @entity603 , and MRI erosions were detected in 21 bones (10 @entity1 ). 6 (29%) of these, distributed among two @entity1 , were seen on x ray. One x ray erosion was not detected by MRI. At 1 year, MRI and x ray detected 15 and 8 new erosions, respectively, and 19% of MRI erosions at baseline had progressed to x ray erosions. In bones with MRI erosions at baseline, the relative risk of having x ray erosions at the 1-year follow-up was 12.1, compared with bones without @entity2996 (lesion-centred analysis). If bones with baseline x ray erosions were excluded, the relative risk was 5.2. In @entity1 with @entity79 or @entity4 , the relative risk of having x ray erosions at 1 year was 4.0, compared with @entity1 without these signs at baseline ( @entity1 -centred analysis). CONCLUSION: In this group of @entity1 with early @entity309 who were treated uniformly, baseline @entity2996 in MCP or wrist bones markedly increased the risk of x ray erosions at the 1-year follow-up. Low-cost, low-field dedicated extremity MRI is promising for assessment and prognostication of early @entity309 .
