MR imaging uses a powerful magnetic field, radio frequency pulses
and a computer to produce detailed
pictures of organs, soft tissues, bone
and virtually all other internal body structures. The images can then be examined on a computer monitor, printed or copied to CD. MRI does not use ionizing radiation (x-rays).
MR angiography (MRA) is used to examine blood vessels in key areas of the body, including the:
brain
kidneys
pelvis
legs
lungs
heart
neck
abdomen
