Tests and diagnosis

By Mayo Clinic Staff

A meningioma may be detected on an imaging test, such as:

  • Computerized tomography (CT) scan. CT scans take X-rays that create cross-sectional images (like slices) of your brain and head. These images are combined together by a computer to create a full picture of your brain. Sometimes an iodine-based dye is used to augment the picture.
  • Magnetic resonance imaging (MRI). With this imaging study, a magnetic field and radio waves are used to create cross-sectional images of the structures within your brain. MRI scans provide a more detailed picture of the brain and meningiomas.
