[How dangerous is lumbosacral myelography with water-soluble contrast media? (author's transl)].

In the exact diagnosis of space-occupying processes of the lumbosacral spine myelography with water-soluble contrast media is unsurpassed.

However, after 2500 exclusively in-patient lumbosacral myelographies and after a prospective study of 100 patients we were able to demonstrate that this investigation is only slightly dangerous.
