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.
