Computerized tomography (CT) is a diagnostic imaging test used to create detailed images of internal organs, bones, soft tissue, and blood vessels. The cross-sectional images generated during a CT scan can be reformatted in multiple planes, and the scanner can even generate three-dimensional images which can be viewed on a computer monitor, printed on film, or transferred to electronic media.
CT scanning is often the best method for detecting many different cancers since the images allow your doctor to confirm the presence of a tumor and determine its size and location. CT is fast, painless, noninvasive, and accurate. In emergency cases, it can reveal internal injuries and bleeding quickly enough to help save lives.
Please note, you’re briefly exposed to ionizing radiation. The amount of radiation is greater than you would get during a plain X-ray because the CT scan gathers more detailed information. CT scans have not been shown to cause long-term harm, although there may be a very small potential to increase your risk of cancer.
CT scans have many benefits that outweigh this small potential risk. We use the lowest dose of radiation possible to obtain the needed medical information. Also, newer, faster machines and techniques require less radiation than was previously used.
