Myelography with metrizamide in the cervical region.

Cervical myelography with metrizamide (Amipaque) was performed in 72 instances by lateral cervical puncture between C1 and C2, and in 21 instances by lumbar injection. A slight but significant difference in adverse reactions following the two methods was found. On comparing lumbar and cervical myelography using the lumbar approach a significantly higher incidence of nausea and vomiting following the cervical examination was demonstrated. No serious reactions occurred after either the lumbar or the cervical approach.
