Sorry, no etymologies found.
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.
There's a whole world of websites that dope their meta tags with words like 'exorcist' and 'myelogram', websites that want folks like me to come take a look in the hope that here, at last, I will find some commentary on Linda Blair's myelogram.
