Myelography using pantopaque in greater than usual amount with a variation in technique, which is described, is believed to provide increased accuracy in differential diagnosis and precise localization of lesions in the lumbar spine. The need for multiple space exploration is eliminated and more detailed information concerning the size and shape of lesions is provided as compared to that secured by the use of 3 or 6 cc. of opaque medium and fluoroscopic examination alone. In 53 cases in which lumbar myelography was performed and the diagnosis verified or disproved at operation, there was a 5 per cent diagnostic error in 41 instances in which the method outlined was used, as compared with 17 per cent error in 12 cases in which only 3 or 6 cc. of radiopaque material and fluoroscopy alone were used. The accuracy of the procedure would appear to warrant its use in the evaluation of patients suspected of having abnormalities of the lumbar discs associated with nerve root compression.
使用超过常规剂量的泛影葡胺进行脊髓造影，并采用一种已描述的技术变体，据信这种方法能提高腰椎病变鉴别诊断的准确性以及病变的精确定位。与仅使用3或6毫升不透明介质及荧光透视检查相比，它消除了多次探查间隙的需要，并提供了有关病变大小和形状的更详细信息。在53例行腰椎脊髓造影且手术时诊断得到证实或排除的病例中，采用所述方法的41例中有5%的诊断错误，而仅使用3或6毫升不透光材料及荧光透视检查的12例中有17%的错误。该检查方法的准确性似乎使其适用于评估怀疑患有与神经根受压相关的腰椎间盘异常的患者。
