CTM观察正常臂丛神经根的初步报告

Observation of normal brachial plexus root by CT myelography: a preliminary report

目的 探讨脊髓造影CT薄层扫描 (computedtomographymyelography ,CTM)诊断臂丛神经根损伤的可行性。方法 对 1996年 10月至 1999年 5月 ,因其它疾病做颈脊髓造影CT薄层扫描的 5 3例患者 ,观察CT片上臂丛神经根的结构及造影后的副作用。结果 脊髓造影CT薄层扫描片上 ,能清晰地显示神经根 ,经腰穿注入第三代非离子造影剂后不良反应少而轻。

Objective To investigate the possibi1ity of thin section CT myelography in the diagnosis of rootlet avulsion of brachial plexus. Methods We observed the normal brachial plexus rootlet structure of 53 individuals with thin section CT myelography during October, l996 and May, l999 and recorded the adverse reactions of contrast medium. Results Thin section CT myelography visualizes the rootlet inside the spinal cord clearly. The adverse reactions of third generation non ionic water soluble contrast medium were low and mild. Conclusions Thin section CT myelography helps to give an accurate diagnosis of brachial plexus root avulsion inside the spinal cord.
