Is a Shunt Right for You? Idiopathic Intracranial Hypertension

Overview

To determine whether a shunt is right for you or your family member, your healthcare provider will use one or more diagnostic tests.

Diagnostic Procedures

There are several tests that can help to decide whether you are a candidate for a shunt. These same studies can also help evaluate the shunt in case of malfunction or infection.

Brain Imaging

You may have one of the following methods of brain imaging done1:

  • Magnetic resonance imaging (MRI) is a non-invasive diagnostic tool that uses radio signals and a magnet to form computer images of the brain, ventricles, and spine.
  • Computerized (axial) tomography (CAT or CT) scans are special x-ray techniques, which outline the ventricles and other structures of the brain in cross section.

Your physician will decide which type of brain imaging will work best in your situation.
