We applied CT gas myelography at the cervical spinal region and investigated the clinical value of CT gas myelography as a supplementary diagnostic method for the spinal cord and vertebral diseases. Fundamental studies of the conditions of window width and window height and the permitted limit of the angle of incidence were made with phantoms of human neck to establish proper conditions of these factors. In clinical studies, 23 adult persons, who had no abnormality in the cervical spine and in the cervical spinal cord were observed to have normal CT gas myelograms of the cervical region, whereas 37, of clinical cases including 18 of cervical spondylosis, 10 of OPLL, 2 of cervical discopathy, 3 of fracture and dislocation of the cervical spine, 2 of cervical vertebral tumor and 2 of CYL, were found to show clear pathologic findings in the cross sections of the vertebral foramen, subarachnoidal space and spinal cord on the CT gas myelograms. The representative cases of these diseases were presented. The gas myelograms were morphologically classified and investigated in relation to the clinical findings. From the result of these investigations, CT gas myelography appears to be highly useful as a supplementary diagnostic method for diseases of the cervical spine and the cervical spinal cord. Furthermore, we compared the effect of this method with that of CT myelography using metrizamide, a recently developed water-soluble contrast medium.
我们对颈椎区域应用了CT气体脊髓造影，并研究了CT气体脊髓造影作为脊髓和脊柱疾病辅助诊断方法的临床价值。使用人体颈部模型对窗宽、窗高条件以及入射角允许限度进行了基础研究，以确定这些因素的合适条件。在临床研究中，观察到23名颈椎和颈髓无异常的成年人颈椎区域的CT气体脊髓造影正常，而在37例临床病例中，包括18例颈椎病、10例后纵韧带骨化症、2例颈椎间盘病变、3例颈椎骨折脱位、2例颈椎肿瘤和2例脊髓空洞症，在CT气体脊髓造影上的椎孔、蛛网膜下腔和脊髓横断面显示出明确的病理表现。展示了这些疾病的典型病例。对气体脊髓造影进行了形态学分类，并与临床发现相关联进行研究。根据这些研究结果，CT气体脊髓造影似乎作为颈椎和颈髓疾病的辅助诊断方法非常有用。此外，我们将该方法的效果与使用最近开发的水溶性造影剂甲泛葡胺的CT脊髓造影的效果进行了比较。
