[Computer tomography of the cervical spinal canal following intrathecal enhancement: cervical CT myelography. Studies on technic and the initial results (author' transl)].

Computer tomography of the cervical spinal canal was carried out in 54 patients after the intrathecal injection of metrizamide (CT myelography). In 43 patients this was done after conventional myelography, in eleven it was the primary examination. In 32 patients the examination proved normal and in 22 abnormal. Correlation between the CT findings and conventional myelography was excellent. Quite small intraspinal structures both normal and abnormal, could be demonstrated. CT myelography is particularly valuable for determining the special relationships within the vertebral canal. The procedure can supplement and confirm conventional myelography, for instance round the foramen magnum. Under certain circumstances it may be regarded as the method of choice, since it is simpler for the patient and less likely to produce complications due to the contrast medium.
