if you had contrast dye with the scan, which is likely with the background youre decribing, this could very well have been a reaction. although you are fine now i would call the ordering dr monday and let them know what happened. they will want to keep this in your file for future scans and might want to check some basic labs with kidney functions to make sure no more damage was done. keep drinking lots of water and stay well hydrated. if this happens again today call your dr.
