This is the process of gadolinium release through replacement by other. The new GBCA medication guides were one of the results of a December 19, 2017, FDA safety alert that gave the drug a new class warning. The safety agency has a long history with gadolinium, dating back to 2010 when they first highlighted possible problems from gadolinium for those with kidney failure. The FDA issued the December 2017 safety. When you say allergic to contrast, iodine, shellfish - you are referring to the contrast given for Xrays, which does contain iodine - and yes, this kind of allergy can cause death. The contrast used in MRIs is gadolinium which is NOT iodine. Allergy to it is unusual, but it does occur. Still some MRI centers ask if people are allergic to idodine, shellfish etc
