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

For what purpose the CT imaging

CT imaging is:

- one of the best and fastest tools for studying the chest, abdomen and pelvis because it provides detailed, cross-sectional views of all types of tissue.

- often the preferred method for diagnosing many different cancers, including lung, liver and pancreatic cancer, since the image allows a physician to confirm the presence of a tumor and measure its size, precise location and the extent of the tumor's involvement with other nearby tissue.

Definition of Spiral CT scan

A conventional computerized axial tomography scan (CAT scan or CT scan) is an x-ray procedure which combines many x-ray images with the aid of a computer to generate cross-sectional views and, if needed, three-dimensional images of the internal organs and structures of the body. A CAT scan is used to define normal and abnormal structures in the body and/or assist in procedures by helping to accurately guide the placement of instruments or treatments.
