There are limited data on the reliability of extremity magnetic resonance imaging (E-MRI) in the longitudinal evaluation of rheumatoid arthritis (RA). Our aim was to assess the interreader reliability of the OMERACT RA MRI score in the assessment of change in disease activity and bone erosion scores using 0.2 T E-MRI hand and wrist images from 2 timepoints, evaluated by 3 readers at different international centers. The intraclass correlation coefficients and smallest detectable difference results for the change scores were generally good for erosions and synovitis, but were not acceptable for bone edema. Overall, E-MRI demonstrated ability to detect change comparable to that reported for high-field MRI for erosion and synovitis.
关于四肢磁共振成像（E-MRI）在类风湿关节炎（RA）纵向评估中的可靠性数据有限。我们的目的是评估OMERACT RA MRI评分在评估疾病活动度变化和骨侵蚀评分方面的阅片者间可靠性，使用来自两个时间点的0.2 T E-MRI手部和腕部图像，由不同国际中心的3位阅片者进行评估。变化评分的组内相关系数和最小可检测差异结果对于侵蚀和滑膜炎总体良好，但对于骨水肿则不可接受。总体而言，E-MRI在检测侵蚀和滑膜炎变化方面显示出与高场MRI相当的能力。
