[CT-discography for lumbar disc herniation].

Abstract

1. CTD was carried out on 76 intervertebrae of 66 patients with intervertebral disk hernia and its diagnostic merits were discussed. 2. Views in accordance with CTD and myelography are 85% which shows great importance in the diagnosis of intervertebral disk hernias. 3. CTD depicts the relationship between the intervertebral disk and spinal canal as three-dimensional, and furthermore, across-section image of the intervertebral disk can be obtained which makes it possible to know exactly where the prolapsed region of the hernia is located. This is thought to become extremely useful in the diagnosis of exterior hernias and L5-S hernias which are difficult to detect by myelography. Consequently, it is of great value in supplemental diagnosis, aids in the selection of surgical methods, and can provide other useful information.
