CT (Computed Tomography)

What is a CT Scan?

CT (Computed Tomography) scans use rotating x-ray beams to acquire cross- sectional images of the body. The scan is performed in a ring-shaped machine, usually taking less than a minute to perform. Modern scanners, with the aid of computer systems, can use the cross-sectional images to create 3D images of the internal organs. The images are then reviewed by a radiologist. A CT scan provides a high resolution image of the body and is currently the preferred method for diagnosing many diseases and injuries. CT scans can also be used for pre-operative planning and to monitor recovery from illness.

Preparing for your CT Scan

You may be asked to remove some or all of your clothing and to change in to a scrub top, scrub pants or gown during the exam. You may also be asked to remove jewelry, eye glasses, hearing aids, removable dental
work and any metal objects or clothing that might interfere with the CT images. Women should always inform the technologist if there is any possibility that they are pregnant.
