脊髓损伤的MRI诊断

目的:探讨脊髓损伤的MRI表现。方法：收集脊髓损伤患者90例，其中男68例，女22例，平均年龄35岁。应用GE Signa contour 0.5T(40例）和SIEMENS Open 0.2T（50例）磁共振机，脊柱表面线圈，自旋回波序列做轴位和矢状位T1WI、T2WI扫描，其中10例加作冠状线圈。结果：90例患者共发现各种脊髓损伤106例次，其中脊髓完全、不完全性横断14例次（占13.2％），水肿11例次（10.4％），挫伤、出血27例次（25.5％），受压、扭曲27例次（25.5％），软化16例次（15.1％），萎缩11例次（10.4％）。结论：MRI表现能反映脊髓损伤的形态和病理改变，是评价脊髓损伤的好方法，不仅可以指导治疗方案的选择，还有助于判断预后。

Diagnosis of spinal cord injury with MRI

Objective To study the MRI signs in spinal cord injury. Methods A tatal of 90 cases of spinal cord injury examined with magnetic resonance(MR),40 underwent a GE 0.5T superconducting system and 50 with a SIEMENS Open 0.2T. With spine surface coil, all of them were examined with axial and sagittal spin echo sequences, while 10 given extra coronal sequence. MRI findings and its correlation with prognosis of patients were analyzed. Results Among the 90 cases of spinal cord injury, incomplete and complete transection of spinal cord was found in 14 cases (13.2%), spinal cord edema in 11 (10.4%), intraspinal cord hemorrhage in 27 (25.5%), compression and dislocation in 27(25.5%), malacia in 16(15.1%), and atrophy in 11(10.4%). Conclusion From the morphologic and pathological changes of spinal cord MRI can not only direct the option of treatment protocols, but may also evaluate the prognosis of spinal cord injuries. Demonstrated by MRI, it suggests that.
