Ⅲ period: rotator cuff tear.肩袖撕裂。 Often occur in more than 45 years old. 常发于45岁以上。
☆Best location: being is 1 cm, from the hills muscle to变主要为肩袖相关病变和肩关节不稳定。对于 肩袖相关病变，肩关节MRI 常规扫描可作为首选；对于肩关 节不稳定和盂唇病变，则一般首选肩关节MRI 造影进行评价。

常见疾病名称
Rotator cuff tendons disease肩袖肌腱病
Rotator cuff tear肩袖撕裂
生于胶原血管病患者
Can be acute, but more often repeated attacks on the basis of the already suffer from tendon disease可急性发生，
但更常在已患有肌腱病的基础上反复发作
Tendon thickening, hardening; Partial or total disruption; Some tear on slippery bursa, articular surface or in the stroma肌腱增厚、硬化；部分或完全中断；部分撕裂可

在滑囊面、关节面或间质中
Collagen degeneration, but there is no inflammatory cells, chronic tendon can appear in fatty infiltration
胶原变性，但没有炎性细胞，慢性肌腱撕裂中可出现脂肪浸润

一、 Rotator cuff tendons disease 肩袖肌腱病
Etiology pathology 病因病理：
部分撕裂，在肌腱中可见水样信号，但只是部分肌腱受累
Tendon full-thickness tear, liquid into tendon fractures, with varying degrees of tendon retraction肌腱全层撕裂，液体进入肌腱裂隙中，伴不同程度的肌腱回缩
Background 背景
Shoulder disorders mainly involve rotator cuff diseases and shoulder instability. For rotator cuff diseases, routine shoulder MR imaging as the first choice can solve most of the problems in practice. For shoulder instability and related glenoid labrum lesions, shoulder MR arthrography is the first selection for evaluation
