Brain MRI - About the Exam

Mountain Medical performs brain magnetic resonance imaging (MRI) to help diagnose conditions such as:

  • brain tumors
  • stroke
  • developmental anomalies
  • hydrocephalus — dilatation of fluid spaces within the brain (ventricles)
  • causes of epilepsy (seizure)
  • hemorrhage in selected trauma patients
  • certain chronic conditions, such as multiple sclerosis
  • disorders of the eye and inner ear
  • disorders of pituitary gland
  • vascular problems, such as an aneurysm (a bubble-like expansion of the vessel), arterial occlusion (blockage) or venous thrombosis (a blood clot within a vein)

Radiologists also use the brain MRI examination to detect abnormalities in patients with dementia, a disorder that can cause confusion or memory loss.

What you can expect during a brain MRI:

  • You will be asked to lie on the examination table that will move through the center of the MRI magnet.
  • When the examination is completed, you may be asked to wait until the technologist or radiologist checks the images in case additional images are needed.
  • MRI exams generally include multiple runs (sequences), some of which may last several minutes.
  • The entire examination is usually completed within 45 minutes.
