What is MRI?

Picture

Magnetic Resonance Imaging (MRI) uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. The detailed images allow physicians to better evaluate parts of the body that cannot be adequately assessed with other imaging methods such as x-ray, computed tomography (CT or CAT scanning) or ultrasound.


During an MRI test, the area of the body being studied is placed inside the magnet and digital images are produced by the computer which are stored and reviewed by a radiologist. If necessary, a contrast material called Gadolinium may be used to show abnormal tissue more clearly.

MRI is used to evaluate:
  • Bones and joints
  • Spinal conditions
  • Brain conditions such as tumors, aneurysms and nerve injury
  • Problems of the eyes, optic nerves, ears and auditory canals
  • Blood vessels, veins and arteries
  • Heart valves and coronary blood vessels
  • Organs of the abdomen and pelvis
  • Reproductive organs
