MRI - What is it?
Magnetic Resonance Imaging is a method of obtaining pictures of the human body, using a strong magnet and a radio transmitter. It avoids the risk from radiation associated with x-rays, which are traditionally used for looking at the bony parts of the body. MRI allows the non-bony parts to be seen with astonishing clarity, from any angle. The uses of MRI are gradually increasing, and it is routinely used to visualise the brain, spinal cord, joints and some blood vessels.
