The contrast media used for myelography.

A review of the contrast media used for myelography and radiculography is presented. Water-soluble, nonionic medium like metrizamide enables the examination of the entire CSF space. The relation of the diagnostic benefit to complications when using this contrast medium is favorable. Attention must be paid in using the correct myelographic technique and in controlling the possible severe adverse reactions which appear in 1.5% of the cases during 24 h after the examination.
