Magnetic resonance imaging

A method of imaging of the body that allows the organs to be viewed in 'slices.

Magnetic Resonance Imaging (MRI) Scans resemble an X-ray but has some important differences:

  • radiation is not used. Instead the limb is placed inside a magnetic coil, and the alignment of cellular charge to the magnet allows an interpretation to be made by computer as to the structure, and to some extent composition, of the body tissues.
  • images are taken in 'slices' as if your leg has ben sliced, so that adjacent images show the tissues a few millimetres apart from one another.
  • soft tissues are shown up well, and bones less well.
