Computerized Tomography (CT)

The CT, or "computerized tomography," scan is an x-ray procedure that produces detailed cross-sectional images of the body. Instead of taking one picture, as does a conventional x-ray, a CT scanner takes many pictures as it rotates. A computer then combines these pictures into an image of slices of the targeted anatomy.

This test is very useful in identifying many types of liver tumors. After the first set of pictures is taken, the patient often receives an intravenous injection of a radiocontrast agent, or special dye, that helps better outline structures in the body. Making use of this visual enhancement, a second set of images will then be taken.

CT scans take longer than regular x-rays and the patient is required to lie still on a table while they are being done.
