Methiodal

Methiodal is a pharmaceutical drug that was used as an iodinated contrast medium for X-ray imaging.[1] Its uses included myelography (imaging of the spinal cord); for this use, cases of adhesive arachnoiditis have been reported, similar to those seen under the contrast medium iofendylate.[2]
