Different: X-ray (CT) contrast is iodine based and allergic reactions are fairly common. MRI uses Gadolinium which is completely different and allergic reactions are rare. Here is a reference: http://www.medicalnewstoday.com/releases/92774.php I'm not aware of any cross-reactivity but the radiologist supervising your study will know for sure. Mention your previous reaction to them.
