OBJECTIVE
The aim of this study was to determine the reliability of an MRI-based score that evaluates forefoot bursae (FFBs) in patients with RA.
METHODS
Items for inclusion, grading criteria and MRI sequences were determined iteratively. The score was evaluated in 30 patients with established RA. Reader agreement was evaluated using the percentage of exact/close agreement, Bland-Altman plots, kappa and intraclass correlation coefficient analyses.
RESULTS
The FFB score assesses nine forefoot regions and contains four items: presence, shape, enhancement and magnetic resonance characteristics. The FFB score showed moderate to good intra- and interreader agreement (κ range = 0.5-0.9 and 0.47-0.87, respectively).
CONCLUSION
The FFB score is adequately reliable in the evaluation of bursa-like lesions of the forefoot in patients with RA.
目的
本研究旨在确定一种基于MRI的评分在评估类风湿关节炎（RA）患者前足滑囊（FFB）时的可靠性。
方法
反复确定纳入项目、分级标准和MRI序列。对30例确诊为RA的患者进行该评分评估。使用完全/近似一致百分比、Bland-Altman图、kappa和组内相关系数分析来评估阅片者间的一致性。
结果
FFB评分评估九个前足区域，包含四个项目：存在情况、形态、强化及磁共振特征。FFB评分在阅片者内和阅片者间显示出中度到良好的一致性（κ值范围分别为0.5 - 0.9和0.47 - 0.87）。
结论
FFB评分在评估RA患者前足滑囊样病变时具有足够的可靠性。
