PURPOSE
To evaluate the inter-rater agreement for description of labral tears and measures of femoroacetabular impingement (FAI) on 3 T hip MR arthrography.
MATERIALS AND METHODS
53 hip MR arthrograms were reviewed by three musculoskeletal radiologists. Labral tears were described (Czerny classification) with extents recorded. Cam- and pincer-type FAI measures were performed. Intraclass correlation (ICC) and kappa statistic (κ) assessed inter-observer agreement.
RESULTS
There was fair agreement for labral tear description (κ = 0.25-0.39) and for alpha angles (ICC = 0.54), and fair to excellent agreement for other measures of FAI (ICC = 0.51-0.90).
CONCLUSION
There is moderate inter-observer variability reporting labral tears and measures of FAI.
目的
评估在3T髋关节磁共振关节造影中，不同观察者对盂唇撕裂的描述以及股骨髋臼撞击（FAI）测量结果的一致性。
材料与方法
三位肌肉骨骼放射科医生对53例髋关节磁共振关节造影进行了评估。描述盂唇撕裂情况（采用Czerny分类法）并记录其范围。进行凸轮型和钳夹型FAI测量。组内相关系数（ICC）和kappa统计量（κ）用于评估观察者间的一致性。
结果
在盂唇撕裂描述（κ = 0.25 - 0.39）和α角（ICC = 0.54）方面一致性一般，而在FAI的其他测量方面一致性为中等至良好（ICC = 0.51 - 0.90）。
结论
在报告盂唇撕裂和FAI测量结果时，观察者间存在中度变异性。
