Computerized axial tomography

A computerized axial tomography (CAT) scan uses X-rays to image the body’s internal structures, taking a large number of precise images to show regions not visible on a standard X-ray. By pinpointing structures and lesions, the CAT scan enables the physician to make a diagnosis.

The camera rotates around the person and takes many photos with an emitter. These are then sent to a computer, which analyses them and forms an image consisting of a series of cross-sections of the area of interest.

Depending what structures are to be imaged, an oral or intravenous contrast agent may be administered.

How do I access the services?
