    I think a web search might give more info than me (truly!) but I'll give it a shot:
    MRI is Magnetic Resonance Imaging, not X-rays. Any part of the body can be scanned, not just the brain. It is helpful for diagnosing pituitary tumors (often missed in CT), other tumors, multiple sclerosis . . . see http://tjsamson.client.web-health.co...dures/mri.html
    EEG is Electroencephalogram. It follows and graphs brain wave activity, is usually done in awake and asleep states. see http://www.nervus.is/nervus/eeg/abouteeg.htm
    CAT is Computerized Axial Tomography. It is taking X-rays with a sophisticated unit that images the body in slices, like bread. see http://www.emedicinehealth.com/articles/11618-1.asp
    PET scans: see http://www.healthcare.ucla.edu/vital...article_id=300 (I have no personal experience with PET scanners)

    Hopefully now you have a little info to go on! Best, -- D
