Computed tomography (CT) of the thoracic and cervical spine was carried out after lumbar intrathecal introduction of a water-soluble radiographic contrast medium (metrizamide). By choice, no head-down position of the patient was used to facilitate craniad movement of the contrast medium; rather, advantage was taken of the normal CSF flow. This technique, referred to as computer-assisted myelography (CAM), permits the demonstration of the metrizamide-containing subarachnoidal spaces surrounding the thoracic and cervical cord. Some examples of the diagnostic possibilities of the method are discussed.
在腰椎鞘内注入水溶性放射造影剂（甲泛葡胺）后，对胸段和颈段脊柱进行了计算机断层扫描（CT）。我们特意未采用患者头低脚高位来促进造影剂向头侧移动；而是利用了脑脊液的正常流动。这种技术被称为计算机辅助脊髓造影（CAM），它能够显示围绕胸段和颈段脊髓含甲泛葡胺的蛛网膜下腔。文中讨论了该方法在诊断方面的一些可能性实例。
