There are various types of cat scan dye, but I don't remember all the names. The drug most widely used can cause skin issues and breathing problems during the scan. However, your Mother might want to ask her doctor to provide benedryl and predisone to conteract the allergies from the cat scan dye. She could also ask the doctor and/or the technicians to slow down the dye infusion during the scan if she does not want to have the scan without the contrast dye.
