Examples
-
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.
-
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.
-
In certain instances the physician may recommend that both tests (a myelogram and an MR examination) be performed.
-
A CT scan is routinely performed after the myelogram in order to provide cross sectional information.
-
In those individuals who cannot tolerate MRI scanning because of claustrophobia or contraindications, such as a pacemaker, a myelogram is an extremely useful examination.
-
A myelogram provides detailed information about the spinal cord and the nerve roots.
-
An MRI can provide much of the same information as a myelogram without an injection of contrast.
-
A myelogram is performed by placing a needle in the lower back or occasionally in the neck.
