肩关节常见疾病MRI 诊断Ⅰ
常见疾病名称
Rotator cuff tendons disease肩袖肌腱病 Rotator cuff tear肩袖撕裂 Subscapularis rupture肩胛下肌断裂 Acromioclavicular joint disease肩锁关节病 The sub-acromial shoulder impingement syndrome肩
Partial tear, visible water signal in the tendons, but only partial tendon involvement
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
cuff tendon lesions 肩袖肌腱病变的NEER
分期 Ⅰ period: rotator cuff, especially hills tendon
edema and hemorrhage肩袖特别是岗上肌腱水肿和出血Tendonitis or inflammatory lesions, it is better to send in less than 25 years old young man. reversible肌腱炎
最好发部位：岗上肌距大结节附着点1cm处（无血管分布）。

OMnRIa表ll现pulse sequence, signals are increased在所有
脉冲序列上，信号均增高
Tendon thickening, signal not usually homogeneous肌腱常常增厚、信号不均匀
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
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 the greater tuberosity attachment points (no vascular distribution).

或炎性病变，最好发于小于25岁的青年人,可逆.
Ⅱ period: inflammation further progress and more fibrous tissue formation炎症进一步进展及更多的纤维组织形 成Happens at 25～45 years old.好发于25-45岁。
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
NEER in installment of rotator
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
Tendon full-thickness tear of the chronic patients to merge muscle fat atrophy肌腱全层撕裂的慢性患
者可合并肌肉脂性萎缩
