比较常规3T MRI与1.5T MR关节造影（MRA）对临床股骨髋臼撞击（FAI）患者的诊断准确性。68例临床FAI患者接受了1.5T MRA和3T MRI。由两名肌肉骨骼放射科医生前瞻性分析影像学，对患者结局不知情，并对包括盂唇和软骨异常在内的内部紊乱进行评分。通过kappa分析评估观察者间的差异。39名患者随后接受了髋关节镜检查，并分析了手术结果和放射学检查结果。与1.5T MRA相比，两名阅片师使用3T MRI检测盂唇撕裂的灵敏度更高（无统计学显著性p=0.07）。对于髋臼软骨缺损，与1.5T MRA相比，两名阅片者使用3T MRI的敏感性具有更高的统计学显著性（p=0.02）。与3T MRI相比，两名阅片师使用1.5T MRA检测分层的灵敏度略高，但这些差异无统计学显著性（p=0.66）。除分层识别外，所有参数的观察者间一致性均为实质至完美一致（3T MRI显示中度一致性，1.5T MRA显示实质一致性）。常规3T MRI对髋臼唇的检测至少与1.5T MRA相当，对疑似FAI患者的软骨缺损的检测可能上级于1.5T MRA。·常规3T MRI诊断盂唇撕裂与1.5T MRA相当。 ·常规3T MRI对髋臼软骨缺损的诊断优于1.5T MRA，具有上级诊断价值。 ·常规3T MRI诊断软骨分层与1.5T MRA相当。 ·进行手术的组中症状严重程度评分显著更高（p<0.05）。
To compare the diagnostic accuracy of conventional 3T MRI against 1.5T MR arthrography (MRA) in patients with clinical femoroacetabular impingement (FAI). Sixty-eight consecutive patients with clinical FAI underwent both 1.5T MRA and 3T MRI. Imaging was prospectively analysed by two musculoskeletal radiologists, blinded to patient outcomes and scored for internal derangement including labral and cartilage abnormality. Interobserver variation was assessed by kappa analysis. Thirty-nine patients subsequently underwent hip arthroscopy and surgical results and radiology findings were analysed. Both readers had higher sensitivities for detecting labral tears with 3T MRI compared to 1.5T MRA (not statistically significant p=0.07). For acetabular cartilage defect both readers had higher statistically significant sensitivities using 3T MRI compared to 1.5T MRA (p=0.02). Both readers had a slightly higher sensitivity for detecting delamination with 1.5T MRA compared to 3T MRI, but these differences were not statistically significant (p=0.66). Interobserver agreement was substantial to perfect agreement for all parameters except the identification of delamination (3T MRI showed moderate agreement and 1.5T MRA substantial agreement). Conventional 3T MRI may be at least equivalent to 1.5T MRA in detecting acetabular labrum and possibly superior to 1.5T MRA in detecting cartilage defects in patients with suspected FAI. • Conventional 3T MRI is equivalent to 1.5T MRA for diagnosing labral tears. • Conventional 3T MRI is superior to 1.5T MRA for diagnosing acetabular cartilage defect. • Conventional 3T MRI is equivalent to 1.5T MRA for diagnosing cartilage delamination. • Symptom severity score was significantly higher (p<0.05) in group proceeding to surgery.
