Get To Know What Cranial Computed Tomography Is All About?
A cranial computed tomography (CT) scan is an imaging method that uses x-rays to create cross-sectional images of the head, including the skull, brain, eye sockets, and sinuses.
Generally a cranial CT scan is recommended to help diagnose or monitor the following conditions:
During the test, the patient is asked to lie on a narrow table that slides into the center of the CT scanner. Cranial computed tomography produces images from your upper neck to the top of your head. During the test, you have to be still, because any kind of movement will cause blurred images. Inside the scanner, the machine's x-ray beam rotates around the patient. Small detectors inside the scanner evaluate the amount of x-rays that make it through the part of the body being examined. This information is used by the computer to create several individual images, called slices. These images can be stored, viewed on a monitor, or printed on film. Three-dimensional models of your head can be created by stacking the individual slices together. Often a contrast material is used to highlight blood vessels and look for a tumor.
