肩关节常见疾病MRI诊断-Ⅰ.ppt

斜失 T1WI 轴位MR arthrogram T1WI： Most of below the shoulder tendons (long arrow) is missing, the following small still attached(arrow).肩胛下肌腱大部份（长箭头）缺失，下面小部分仍附着（箭头）。 MR arthrogram：Below the shoulder tendons, small part is still attached to the nodules (arrows).肩胛下肌腱下面小部分仍附着于小结节（三角箭头）。 斜失 T1WI 轴位 MR arthrogram T1WI： Below the shoulder tendons completely missing (long arrow).肩胛下肌腱完全缺失（长箭头）。 MR arthrogram：Below the shoulder tendons (white arrow) has moderate retraction.肩胛下肌腱（白箭头）已中度回缩 斜失 T1WI MR arthrogram 轴位MR arthrogram Oblique sagittal :T1WI MR arthrogram ：造影剂进入小结节（箭头）。 Transverse MR arthrogram：造影剂进入小结节（箭头）。 斜失 T1WI 3级： 68 Y，F. subscapularis head part fat atrophy (long arrow), the following muscle is normal.肩胛下肌头部部分脂肪萎缩（长箭头），下面肌肉正常。 3级:43Y,M. Subscapularis almost entirely atrophy (arrow), fat instead of muscles.肩胛下肌几乎完全萎缩（箭头） ，脂肪代替肌肉。 斜失 T1WI Fig 7 Full thickness tear of the subscapularis.肩胛下肌腱全层撕裂。 Axial MR arthrographic image shows the complete discontinuity and retraction of the tendon (arrow).MRI造影轴位，示肩胛下肌腱连续性中断，断端回缩(箭) Name of common diseases, including 11 type, today we mainly study… * T1WI：Hills (large arrows) tendons signal increase without thinning, irregular or interrupt; At the same time we can see under the deltoid fat layer (the small arrow)岗上肌腱信号增加（大箭头），无变薄，不规则或中断；同时可以看到三角肌下脂肪层（小箭头） T1WI: hills tendon diffuse higher signal (large arrows), tendon thinning, irregular, and humerus head at the front of the greater tuberosity fracture pressure (small arrow); On T2WI sequence: short T1 signal ,performance is below the shoulder peak - below the deltoid synovial sac effusion (solid arrow), while the visible head of biceps tendon peritendineum effusion (hollow arrows).T1WI：岗上肌腱弥漫性信号增高（大箭头），肌腱变薄、不规则，同时肱骨头大结节前部骨折压迫（小箭头）； T2WI：T1高信号表现为肩峰下-三角肌下滑囊积液（实心箭头），同时可见肱二头肌腱腱鞘积液（空心箭头）。 * 2：Some article fiber cable covers nodules (black arrow). Dislocation of the biceps tendon of long head is moderate. Located on the humerus head and glenoid cavity lip (long arrow). Hume
