Maybe: Ct contrast agents is usually iodinated and are classifed as either ionic or non-ionic. Some are more allergy-prone than others. Ct scan contrast is totally different than MRI contrast. In contrast, MRI contrast agents usually contains chelated gadolinium. Tell the radiologist about your previous ct scan contract allergic symptoms when getting your mri.
