Brain MRI

What is a brain MRI exam?

Magnetic resonance imaging (MRI) uses a magnetic field and radio waves to produce clear, detailed images of your internal organs, tissues, and joints. A brain MRI can help your physician diagnose and evaluate many brain-related conditions.

Why has my physician ordered this exam?

Your physician may call for a brain MRI to diagnose, assess, and/or monitor a variety of conditions, including:

  • Brain tumor
  • Dementia
  • Disease of the pituitary gland
  • Multiple sclerosis
  • Stroke
  • Tissue abnormalities, when eye or inner ear disease is present

What might prevent my physician from ordering this exam?

Some metals interfere with MRI equipment. Be certain your physician knows if you have:

  • Aneurysm clips
  • Implanted neurostimulator
  • Inner-ear implants
  • Metal fragments in your eye(s)
  • Pacemaker/defibrillator
  • Pacing wires
  • Transcutaneous electrical nerve stimulation (TENS) unit
