Diagnosing Headaches

A CT scan of the head may be recommended if you are getting daily or almost daily headaches.
A CT scan can help your doctor rule out other causes of headaches, such as:
- Brain tumor
- Abscess (an infection of the brain)
- Hydrocephalus (the abnormal buildup of cerebrospinal fluid in the brain)
- Sinus blockage
- Injuries
- Aneurysm or bleeding in the brain
A CT scan is not able to diagnose migraines.
