Cervical myelography with metrizamide.

In 177 patients 190 cervical myelographies were performed, 52 after cervical and 138 after lumbar puncture. While the last-mentioned technique may be considered as the safest, the first-mentioned appears to cause less adverse reactions and also offers films of higher quality. The cooperative ability of the patient as well as the shape of the spine must be considered for selecting the site of puncture. Films are obtained permitting high diagnostic accuracy with regard to lesions involving root sleeves and to the presence of intramedullary or extramedullary lesions, in particular protrusions and disc herniations.
