MRI Defined
  • A non invasive method used to render images of
    the inside of an object. It is primarily used in
    medical imaging to demonstrate pathological or
    other physiological alterations of living
    tissues.
  • Cost between 1 m and 3 m US
  • One advantage of an MRI scan is that it is
    harmless to the patient. It uses strong magnetic
    fields and non-ionizing radiation in the radio
    frequency range.
  • While CT provides good spatial resolution (the
    ability to distinguish two structures an
    arbitrarily small distance from each other as
    separate), MRI provides comparable resolution
    with far better contrast resolution (the ability
    to distinguish the differences between two
    arbitrarily similar but not identical tissues).
