It then Stops the radio waves and ?listens? to the bodies electromagnetic transmissions at the selected frequency. The transmitted signal is used to create images much like those of the CAT scans, but are far more accurate and much easier to interpret. In current practice, the MRI is preferred for diagnosing most diseases of the brain and central nervous system. And is the best diagnostic technique we know.
