Subsctients with rotator cuff tear, imaging examination, should be a comprehensive observation of rotator cuff and the
肩胛下肌断裂 surrounding structure可疑肩袖撕裂的病人行影像学检查时需对肩袖及其周围结构作全面观察:
HAGL Rotator cuff tear
肩胛下肌腱下面小病部分变仍（附着盂于小肱结下节（韧三角带箭肱头）骨。 部撕脱）
Labrum cyst 盂唇囊肿
Adhesive capsulitis joints粘连性关节囊炎
Shoulder joint osteoarthrosis肩关节骨关节病

The sub-acromial shoulder impingement 注意撕裂口大小、肌腱受累范围、肌腱边缘情况、肌肉萎缩及骨骼改变等。
Etiology pathology 病因病理：

峰下撞击综合征 部分撕裂，在肌腱中可见水样信号，但只是部分肌腱受累
Coronal oblique MR images of the shoulder show fluid in the dilated subdeltoid–subacromial bursa (arrow head).
Sagittal oblique image shows a Type II acromion and a degenerative spur at the anteroinferior edge of the acromion (arrow).

Etiology pathology 病因病理：
Excessive use, lead to degeneration and tear of rotator cuff 过度使用导致肩袖的退行性变和撕裂
Most often in impingement最常继发于撞击综合征 Can occur in patients with collagen vascular disease可发
肩关节常见病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 。

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
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
