目的 评价MSCT和MRI在外伤性肩关节损伤中的诊断价值。方法 对65例外伤性肩关节损伤患者分别进行MSCT和MRI检 查，其中经临床证实包括骨折或隐匿性骨折52例、肩袖撕裂31例、肌肉软组织挫伤65例。结果 MSCT分别发现骨折 49例、肌肉等软组织挫伤者43例、肩袖撕裂2例。MRI检查发现骨折或隐匿性骨折者51例，发现肌肉等软组织挫伤者 65例，发现肩袖撕裂29例。结论 MSCT和MRI在肩关节骨折的诊断上均具有很高的准确率,两者无明显差异， 但在肩 袖撕裂和肌肉软组织损伤的诊断上MRI要优于MSCT。

Objective To evaluate the diagnostic value of MSCT and MRI in traumatic shoulder joint injury. Methods It was included 65 cases of traumatic shoulder joint injury, patients confirmed by clinical with fracture or occult fracture 52 cases , rotator cuff tear 31 cases, and 65 cases had soft tissue contusion of muscle. All patients underwent both MSCT and MRI. Results It was found to 49 cases with fracture, muscle and other soft tissue contusion 43 cases, 2 cases of rotator cuff tear by MSCT examination in all cases. 51 cases of fracture or occult fracture,65 cases of muscle and other soft tissue contusion and 15 cases of rotator cuff tear were confirmed by MRI. Conclusion Both MSCT and MRI had the high accuracy for the diagnosis of shoulder joint fractures , no difference between the two, but in the rotator cuff tear and muscle tissue damage on the diagnosis of MRI is superior to the MSCT.
