| 摘 要： | 目的 分析肌肉损伤的MRI表现.方法 收集我院15例临床怀疑有肌肉损伤的患者MRI资料,其中7例有随访;由两位副主任医师叫顾性对MR图像的征象进行分析.结果 15例患者中13例(87%)发牛在下肢;有5例为肌肉拉伤,T1wI上呈等信号,T2WI、STIR或frFSE FS上则表现为线状或片状的高信号区;10例为肌肉血肿,所有患者在T2WI、STIR或frFSE FS上都表现为高信号,T1WI上3例为低信号,3例为等信号,其余4例为不均匀的稍高或高信号.结论 MRI足肌肉损伤最佳的影像学检查方法.

| Abstract: | Objective To define the MR imaging features of muscle injury. Methods MRI exams of 15 patients with clinical suspicion for muscle injury were reviewed and 7 patients had been followed up. MRI findings of these patients were evaluated by two senior musculoskeletal radiologists retrospectively. Results Thirteen patients (87%) had low-extremity involvement in 15 cases. Five cases were muscle strain and intermediate signal intensity was showed on T1WI and high signal region of the linear or lobed was noted on T2WI and STIR or frFSE FS in injured muscle. Ten cases were intramuscular hematomas and all patients demonstrated the high signal intensity on T2WI and STIR or frFSE FS. But there were different signal intensity on T1WI and 3 cases showed low signal and 3 cases had intermediate signal and the rests showed the confusing slightly high or high signal. Conclusion MRI is one of the best choices for imaging muscle injuries. |
