What does the ink in the fluoroscopy epidural steroid injection transforaminal supposed to look like?

See more here : http://www.conciergeradiologist.com/interventional-radiology.html the wrist arthrogram is the closest example to what the dye ("ink") would look like - i'll try to find an exact image of an epidural steroid injection for you.

Spread centrally: The ideal spread will show the contrast dye spread centrally to the epidural canal and laterally highlighting the nerve path producing a 'characteristic' epidurogram.

Transforaminal Inj: In the transforaminal approach to the epidural steroid injection the nerve is coated with the steroid/anesthetic mixture. Usually the dye can look like its outlining the nerve, outlining the epidural space or even outline both the nerve and epidural space.
