pantopaque

["Barlow, Agnes E." <BarlowAE@MASPO2.MAS.YALE.EDU>]

Specifically, a small number of cc's of pantopaque [contrast agent] is 
injected
[generally] via lumbar puncture into the subarachnoid space of the spinal 
cord.  This is usually done under fluoroscopic control.  The table is tilted 
so that the contrast agent moves up and down in the subarachnoid space. 
 Ruptured discs and other abnormalities show as a deformity pressing on the 
pantopaque- filled space.

The iodine in the contrast agent makes it attenuate radiation and show up on 
fluoro images and "white" on the xray films taken during this myelogram 
procedure.

CT scans have replaced myelograms in many cases.
