What does a cranial CT show?

It also helps your doctor to evaluate your face, sinuses, and skull or to plan radiation therapy for brain cancer.
How is a cranial CT scan performed?
A cranial CT scanner takes a series of X-rays. A computer then puts these X-ray images together to create detailed pictures of your head. These images help your doctor make a diagnosis. The procedure is usually done in a hospital or outpatient imaging center.
What does an abnormal CT scan of the brain mean?

What is a skull CT scan?
A computed tomography (CT) scan of the head is an imaging scan that uses X-rays to develop a 3D image of the skull, brain, and other related areas of the head.
