Abstract：
UNASSIGNED: Currently, there is no consensus regarding the accuracy of magnetic resonance imaging (MRI) in the detection of acetabular chondral delamination (ACD) in patients with femoroacetabular impingement (FAI), and, correspondingly, the preoperative diagnosis of ACD remains challenging.
UNASSIGNED: It was hypothesized that MRI would have relatively high accuracy in detecting ACD in patients with FAI.
UNASSIGNED: Cohort study (diagnosis); Level of evidence, 2.
UNASSIGNED: We retrospectively evaluated patients who attended the sports medicine clinic of our department and underwent arthroscopic surgery for the diagnosis of FAI between January 2018 and December 2020. All patients underwent preoperative 3.0-T MRI. ACD was evaluated by 2 raters on 3.0-T MRI scans, and interrater and intrarater reliability was assessed. Sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) of MRI for diagnosis of ACD were calculated, using arthroscopic surgery as the standard.
UNASSIGNED: A total of 233 patients (mean age, 37.4 years; 99 male and 134 female) were included in this study. The presence of ACD in 101 (43.3%) patients was confirmed during hip arthroscopy. The intraobserver reliability of both of the observers in detecting ACD using 3.0-T MRI scans was almost perfect (observer 1, kappa coefficient [κ] = 0.909 [95% CI, 0.854-0.964]; observer 2, κ = 0.937 [95% CI, 0.890-0.984]), and the interobserver reliability between the observers (κ = 0.801 [95% CI, 0.723-0.879]) was substantial. The overall sensitivity, specificity, PPV, and NPV of preoperative MRI to detect ACD were 83.7%, 82%, 74.2%, and 89.1%, respectively.
UNASSIGNED: It was found that 3.0-T MRI had a relatively high sensitivity, specificity, PPV, and NPV for diagnosis of ACD in patients with FAI and could be a reliable method of diagnosing ACD preoperatively.

摘要：
未经评估：目前，关于磁共振成像（MRI）在股骨髋臼撞击（FAI）患者髋臼软骨分层（ACD）检测中的准确性尚无共识，and,相应地,ACD的术前诊断仍然具有挑战性.
UNASSIGNED：据推测，MRI在FAI患者的ACD检测中具有相对较高的准确性。
未经批准：队列研究（诊断）；证据水平，2.
UNASSIGNED：我们回顾性评估了2018年1月至2020年12月期间在我们部门的运动医学诊所就诊并接受关节镜手术以诊断FAI的患者。所有患者术前均接受3.0-TMRI检查。ACD由两名评估者在3.0-TMRI扫描中进行评估，并评估了评分者和评分者内部的可靠性。灵敏度,特异性，准确度,阳性预测值(PPV)，计算MRI诊断ACD的阴性预测值(NPV),以关节镜手术为标准。
未经批准：共有233名患者（平均年龄，37.4岁；99名男性和134名女性）被纳入本研究。在髋关节镜检查期间证实了101例（43.3％）患者中存在ACD。两个观察者使用3.0-TMRI扫描检测ACD的观察者内部可靠性几乎是完美的（观察者1，kappa系数[κ]=0.909[95％CI，0.854-0.964]；观察者2，κ=0.937[95％CI，0.890-0.984]），观察者之间的观察者间可靠性(κ=0.801[95%CI，0.723-0.879])相当高。整体灵敏度,特异性，PPV,术前MRI检测ACD的NPV为83.7%，82%,74.2%,和89.1%，分别。
UNASSIGNED：发现3.0-TMRI具有相对较高的灵敏度，特异性，PPV,和NPV用于诊断FAI患者的ACD，可能是术前诊断ACD的可靠方法。
