Dimethiodal is the diagnostic aid (radiopaque medium). Dimethiodal sodium was the chemical analog of methiodal sodium with two instead of one iodine atom per molecule. It is an uro-angiographic contrast agent that, together with methiodal sodium, iodomethamate disodium and iodopyracet diethanolamine, dominated the market in 1930s and 1940s.
