    apparently MRI detects atoms and especially hydrogen, bone contains everything except H2 so MRI is good at detecting bleeding around the bone area. just got back from radiology dept
    True? False?

    A few quick points to start you off:

    MRI = no ionising radiation, is good for soft tissue injury and oedema, good anatomical definition, but expensive and takes time to perform a scan, can't do if patient has magnetic metal inside them.
    CT = quicker, better for bony injury, cheaper and faster, but uses high doses of ionising radiation. 1 in 200 scans in a CT will result in a radiation-induced cancer, so they're not something to be done lightly.

    Because it won't help you decide whether you actually want to be a doctor or not, and you'll probably mis-remember things and given that you don't have the background knowledge with which to put it all in context (and won't have until you're a clinical medical student) it is pretty useless. A much better use of your time in a hospital would be shadowing junior doctors, seeing what it is that they really do, and considering whether you are willing to do that job.

    What if the OP is genuinely interested in this kind of thing. And s/he wants to learn about it in addition to experiencing work as a doctor.

    also - more satisfying to get your own answer when it isn't really that hard to find it - what do you think gave me the foot in the door to unfamiliar topics? WIKIPEDIA!!!

    Requesting CTs usually is less painful than MRIs and they're also generally done and reported faster!
