The risk with gadolinium is that it is never fully removed from your system and if you are allergic to it, it means a PERMANENT whole body allergic reaction. Skin itching and incurable chronic pain. It has nothing to do with kidney function.

I got familliar with this condition by a random persons blog who go affected by this during normal MRI and also didn't expect to be part of 1-2%. Unfortunately the blog is now gone, and that post now only lives inside my RSS reader.
