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.

MR imaging of the body is performed to evaluate:1. organs of the chest and abdomen—including the
heart, liver, biliary tract, kidney, spleen, and pancreas and adrenal glands.
2. pelvic organs including the reproductive organs in the male (prostate and testicles) and the female (uterus, cervix and ovaries).
3. blood vessels (MR Angiography).
4. breasts.
