Omnipaque脊髓造影的初步体会

Omnipaque是新型非离子化水溶性造影剂（1），又名Iohexel,三碘三酰苯，碘酞六醇和通用泛影酰苯，自1982年问世以来，文献报道（1－2），它不仅是各种血管造影的优良造影剂，而且也是脊髓造影的首选造影剂，我院自1986年9月至1988年5月共做了Omnipaque脊髓造影40例，现将初步体会报道于后。     

选择性脊髓血管造影

选择性脊髓血管造影系1964年Dichiro首先介绍，自1968年Doppman和Newton等相继提出脊髓疾病的选择性栓塞治疗以来，脊髓血管造影的意义和价值显著提高，本文报告一组34例脊髓血管造影的结果，其中1例还施行了选择性栓塞治疗。     

100例脊髓型颈椎病CT脊髓造影诊断：与常规脊髓造影对照

100 cases of cervical spondylotic myelopathy were studied with both CTM and conventional myelography and the results were compared. It was shown that CTM possesses more advantages over its counterpart as follows: (1) CTM can demonstrate with a higher degree of accuracy the size and configuration of the spinal cord, its internal composition and cystic necrosis, can pick up more herniations, hard and soft, up to 16% (39/252) and better define the position left, middle and right of the protrusion. (2) CTM is capable of making a correct diagnosis of cervical myelopathy and cystic necrosis in the cord. Analysis also showed that the degree of changes of spinal cord seen on CTM correlation closely with severity of the clinical picture. Atrophy and cystic necrosis of the cord are important factors accounting for clinical deterioration and operative failure.     

用Omnipaque作脊髓造影检查的体会附90例分析

目的：报告Ｏｍｎｉｐａｑｕｅ在脊髓造影检查中的应用。资料与方法：回顾分析９０例临床拟诊为椎管内病变,使用Ｏｍｎｉｐａｑｕｅ造影剂进行椎管造７影检查。结果：９０例中,有６例出现副反应,占７％：８４例病 人检查后无任何不良反应２４小时后观察,椎管内造影剂均已吸收,检查中能显示病变范围与郭,优于碘苯脂等油质造影剂。结论用Ｏｍｎｉｐａｑｕｅ作为椎管造影检查,优点多,副作用少,使用方便,值得推广。     

椎管内占位性病变的脊髓造影

目的对比分析脊髓造影、脊髓造影CT及MRI在椎管内占位性病变中的作用.方法对资料完整的64例椎管内占位性病变病人进行了脊髓造影、CTM、MRI影像学比较研究.脊髓造影采用常规脊髓造影和CTM相结合(以下称脊髓造影).CTM在常规脊髓造影后4～6h进行.MRI采用SE序列加GE序列.椎管内占位性病变的病灶检出率、定位和定性准确率做一统计和分析.结果脊髓造影CT与MRI的检出敏感性分别为88.6%,85.7%,定性准确率分别为66.2%,79.6%,定位准确率分别为90.6%,92.3%,病变检出率及定位准确率在造影与MRI之间无显著差异,而定性准确率存在显著差异(P＜0.05).结论脊髓造影CT与MRI结合将有利于椎管内病变的检出、定位及定性能力的提高.     

腰椎间盘脱出的碘苯酯脊髓造影

碘苯酯用于脊髓造影已有较长的历史，尽管目前已较多的应用水溶性碘造影剂，但由于碘苯酯价廉，使用方便，仍较适用于基层医院，本文报导51例腰椎间盘脱出的碘苯酯脊髓造影。     

复发性腰椎间盘突出脊髓造影CT诊断标准

复发性椎间盘突出与瘢痕组织的鉴别诊断至今仍很困难,若无磁共振断层扫描,则普通脊髓造影和脊髓造影CT的联合应用是最好的诊断方法。     

CT脊髓造影诊断椎管内占位病变的意义

The value of omnipaque myelography and CT myelography in 77 cases of intraspinal space-occupying lesions (51 extramedullary and 26 intramedullary confirmed by operation) was reviewed. In 69 cases the preoperative diagnosis was accurate, but not in the other 8 cases. It is not advisable according to the authors' experience to have both myelography and postmyelography CT scan done for all intraspinal space-occupying lesions. For most of the extramedullary tumors, myelography alone proved to be adequate. For intramedullary lesions the information obtained from myelography was inconclusive and postmyelography CT scan as a supplementary procedure was necessary.
