Yeah, a cat scan is pretty much safe. I say 'pretty much' because the ionizing rays cat scans apply can cause DNA which can lead to cancer. Same as X-rays. However, this is very rare, and your doctor would only give you a cat scan/X-ray if he thought you really needed one. What I'm saying here is that, for all practical purposes, cat scans are safe.
CAT or CT scanning can be any of a number of different scan technologies, as CAT stands for Computed Axial Tomography and says nothing about the beams used. In common use, however, CT and CAT scans typically use X-rays, and those that use more exotic techniques are named by the technique they use (PET and NMR scans, for instance).
there isnt a difference moron
The metal that is used as a dye in CT scans is water soluble iodine or barium. These are sometimes avoided by patients because of allergies to the metals.
it helped to locating a safe spot to land on the dusty moon!

Barium is used as a dye during CAT scans.

No, they shouldn't.

CAT scans and MRI scans are often used.
CAT scans and MRI scans are useful for a wide variety of medical investigations; the MRI in particular is very useful for neurological examinations, since it is otherwise very difficult to examine the brain in any detail. CAT scans can be used for all sorts of things, to investigate illness or injury in any part of the body. I had one recently for a kidney stone.
