A patient may receive a CT scan of the head to determine the cause of headaches, weakness in the body or a sudden change of mental state, states KidsHealth. A scan of this region can confirm the presence of brain abnormalities such as bleeding, tumors, cysts or hydrocephalus, a condition in which there is excess fluid in the ventricles of the brain. It is also useful in examining the sinuses, pituitary gland or pineal gland for health problems.

For example, a CT scan can make it easier to place a needle properly when draining an abscess.
