The CAT Scan may be done twice. The iodinated contrast enhanced the vascular structures and improved interpretation of the CAT Scan images. The IV contrast is usually injected with a motor driven power injector and so extravasation from the vein which causes irritation in the skin may sometimes happen. There is also a risk of allergy to the iodinated contrast material resulting in hives, itching, wheezing, shock etc. Again pretreatment with Benadryl and Predisone usually eliminates reaction in allergic patients.
