摘　　要：目的探讨脊髓造影CT(CTM)诊断臂丛神经撕裂伤的临床价值。方法16例臂丛神经损伤患者行CTM。全部患者与临床手术探查对照,7例术前行电生理学检查。结果本组共检出28个受损神经根,其中26个诊断准确,准确率为92.8%。神经根撕裂伤的主要征象是椎管内神经前、后支充盈缺损消失,间接征象为假性硬膜囊肿,脊髓移位与变形,神经根扭曲。结论CTM对臂丛神经根损伤的诊断具有重要价值。Objective To evaluate the value of computed tomography myelography（ CTM ） in diagnosing the laceration of brachial plexus. Methods Sixteen cases with brachial plexus injury underwent thin - slice high resolution CT scanning two hours after the examination of conventional lumber puncture myelographs. The results of CTM in patients were compared with surgical exploretation and seven patients underwent preoperatively electrophysiological examination . Results There were totally 28 nerve roots injury. Of them,26 were detected by CTM ,the accuracy was 92.8%. The main signs of nerve root laceration were the disapperance of the filling defect of ventral and forsal root, the indirect signs were false meningeal cyst,displacement and deformation of spinal cord,twist of nerve root. Conclusion CT myelography is of significant value in diagnosing the laceration of nerve root.
