Are CAT scans dangerous?

Question

I hear that they put a dye into your veins. I already have headaches and allergies to many things so I'm worried that I might have an allergic reaction.to the dye and elevated blood pressure from the tension of the procedure.

Answer 1

CT scans are very safe. It is the equivalent radiation of getting several XRays at once, but XRays wont harm you unless you are getting a lot of exposure over long periods of time (like if you are an XRay technician and you don't protect yourself from exposure).

Answer 2

they are not , they are more safe than X-RAY!
