    Funnily enough I did a job for a CAT scan radiologist the other day and he said one major use of CAT Scans is for acute cases. If you are busy dying from some sudden unknown cause they can stick you in a CAT scanner and straight away spot there is a blockage in an artery in your leg or whatever, and treat it. Whereas an MRI takes like 20 minutes to get sorted out apparently, by which time you may be dead or majorly messed up.

    Typically, the reason that we still use the CAT (now more commonly referred to as CT) is because it has a fast turn-around rate, making it particularly useful in emergency medicine. The downside is that radiation can't image certain structures. It particularly doesn't do as well with soft-tissue imaging.

    Speed. They're faster to do.

    Giving both may get something that using only one doesn't.

    It is important to establish if the patient has any type of surgical implant before subjecting them to MRI scan.

    The need for urgent action, together with a lack of information or an incoherent patient would suggest a CAT scan would be a safer option.

    First and foremost, CAT scans (or CT scans) are cheaper so ideal off the bat. Both MRIs and CT scans can view internal body structures. However, a CT scan is faster and can provide pictures of tissues, organs, and skeletal structure. An MRI is highly adept at capturing images that help doctors determine if there are abnormal tissues within the body. MRIs are more detailed in their images.

    CT are faster and cheaper.

    But MRIs are more detailed.

    A doctor will choose based on which they think they actually need.
