A comment on water-based dyes, by I.H.J. Bourne, MD

In the Journal of the Royal Society of Medicine Vol. 83 April l990 titled Lumbo-sacral Adnesive arachnoiditis: a review in the introduction, the fourth paragraph says:

"In spite of the fact that oil-based iodine agents have been abandoned there is still the risk that water-based iodine preparations will in some way cause arachnoiditis. The present trend towards the use of non-invasive electronic scanning techniques brings hope that myeolgraphy using iodine-based media or indeed any other medium will become a thing of the past."
