CT vs MRI: Ct's and mris can focus on different things. Ct is typically used to view bone and look for bleeding while mris are used to view tissues. Also, cts use radiation similar to xrays while and MRI does not expose the patient to any radiation. However, anyone with a magnetic metal in their body can not get an mri, since MRI uses a large magnet.

Radiation vrs magnet: Cat scanning employs radiation, MRI uses magnet technology. Ct better in looking at bones, larger structures, and MRI better with soft tissue. For brain, skull fracture better visualized with cat, multiple sclerosis plaques seen far better with mri.
