Abstract：
UNASSIGNED: Pathologies of the shoulder, i.e. rotator cuff tears and labral injuries are very common. Most patients receive MRI examination prior to surgery. A correct assessment of pathologies is significant for a detailed patient education and planning of surgery.
UNASSIGNED: Sixty-nine patients were identified, who underwent both, a standardised shoulder MRI and following arthroscopic shoulder surgery in our hospital. For this retrospective comparative study, the MRIs were pseudonymised and evaluated separately by an orthopaedic surgeon and a radiologist. A third rater evaluated images and reports of shoulder surgery, which served as positive control. Results of all raters were then compared. The aim was an analysis of agreement rates of diagnostic accuracy of preoperative MRI by a radiologist and an orthopaedic surgeon.
UNASSIGNED: The overall agreement with positive control of detecting transmural cuff tears was high (84% and 89%) and lower for partial tears (70-80%). Subscapularis tears were assessed with moderate rates of agreement (60 - 70%) compared to intra-operative findings. Labral pathologies were detected mostly correctly. SLAP lesions and pulley lesions of the LHB were identified with only moderate agreement (66.4% and 57.2%) and had a high inter-rater disagreement.
UNASSIGNED: This study demonstrated that tears of the rotator cuff (supraspinatus, infraspinatus) and labral pathologies can be assessed in non-contrast pre-operative shoulder MRI images with a high accuracy. This allows a detailed planning of surgery and aftercare. Pathologies of the subscapularis tendon, SLAP lesions and biceps instabilities are more challenging to detect correctly. There were only small differences between a radiologic and orthopaedic interpretation of the images.

摘要：
■肩膀的病理，即肩袖撕裂和唇膜损伤是很常见的。大多数患者在手术前接受MRI检查。正确评估病理对于详细的患者教育和手术计划很重要。
■确认了69名患者，两者都经历了，在我们医院进行了标准化的肩关节MRI和肩关节镜手术。对于这项回顾性比较研究，MRI由整形外科医生和放射科医生假名评估.第三位评估者评估了肩部手术的图像和报告，作为阳性对照。然后比较所有评估者的结果。目的是分析放射科医生和整形外科医生对术前MRI诊断准确性的一致率。
■与检测透壁袖带撕裂的阳性对照的总体一致性较高（84％和89％），而对于部分撕裂则较低（70-80％）。与术中发现相比，肩胛骨下撕裂的评估具有中等的一致性（60-70％）。检查大部分正确。LHB的SLAP病变和滑轮病变仅具有中度一致性（66.4％和57.2％），并且评分者之间存在很高的分歧。
■这项研究表明，肩袖撕裂（冈上，可以在非对比术前的肩部MRI图像中高精度地评估冈下肌）和唇上病变。这允许手术和术后护理的详细计划。肩胛骨下肌腱的病理，SLAP病变和肱二头肌不稳定性对正确检测更具挑战性。影像的放射学和骨科解释之间只有很小的差异。
