A myelogram is a procedure that involves multiple images obtained after an iodine containing contrast agent was injected into the spinal canal and the sac that contains the spinal cord and nerve roots.
Routine radiographs are usually performed prior to a myelogram.
An MRI can provide much of the same information as a myelogram without an injection of contrast.
In those individuals who cannot tolerate MRI scanning because of claustrophobia or contraindications, such as a pacemaker, a myelogram is an extremely useful examination.
In certain instances the physician may recommend that both tests (a myelogram and an MR examination) be performed.
A myelogram provides detailed information about the spinal cord and the nerve roots.
A myelogram is performed by placing a needle in the lower back or occasionally in the neck.
A CT scan is routinely performed after the myelogram in order to provide cross sectional information.
In order to prepare for a myelogram certain medications should be withheld because they lower the seizure threshold; e.g. anti-depressant medications, Zyban (for smoking cessation), anti-psychotic medications, CNS stimulants, muscle relaxants or any other medication that lowers the seizure threshold.
