Myelography in the thoracic region

Abstract

Myelography in the thoracic region is one of the most valuable diagnostic aids for thoracic myelopathy. But because of special characteristics on anatomy of the thoracic spine, it is rather difficult to get accurate myelographic findings constantly in the thoracic region.
This is to report normal thoracic myelograms in careful investigation of 8 cases and pathological findings in some kinds of thoracic myelopathy such as thoracic osteochondrosis, ossification of the posterior longitudinal ligaments on the thoracic spine and ossification of the yellow ligaments.
Myelography should be performed in prone, supine and lateral positions with sufficient amount of the contrast medium, otherwise irregularities of the dye column are seen quite frequently and that leads to misunderstanding of the findings.
