CT Brain Scan

CT brain scans give doctors a 3-dimensional visual image that provides doctors with detailed information about:

  • brain trauma
  • brain tumors
  • brain cancer
  • brain aneurysms
  • other brain diseases

CT brain scans give doctors more detailed information on such conditions than do regular x-rays (radiographs).

What are CT Brain Scans used for?

CT brain scans can help doctors identify:

  • Brain damage in patients who have suffered injuries to the head
  • Blood clots and/or bleeding in the brains of patients showing symptoms of stroke
  • Location of bleeding in cases of suspected ruptured or leaking aneurysm
  • Brain tumours
  • Enlarged brain ventricles (cavities) in patients with hydrocephalus

CT brain scans can also help doctors:

  • Examine cancers of the brain in preparation for radiation therapy
  • Insert and guide a needle into the brain to obtain a tissue sample of the brain (a brain biopsy)
  • Obtain a three-dimensional image of the brain structures
  • Perform CT angiography
