Computed tomography (CT), sometimes called “computerised tomography” or “computed axial tomography” (CAT), is a non-invasive medical examination or procedure that uses specialised X-Ray equipment to produce cross-sectional images of the body.
Each cross-sectional image represents a “slice” of the person being imaged, like the slices in a loaf of bread.
These cross-sectional images are used for a variety of diagnostic and therapeutic purposes.
Risks and Benefits
When used appropriately, the benefits of a CT scan far exceed the risks. CT scans can provide detailed information to diagnose, plan treatment for, and evaluate many conditions in adults and children. Additionally, the detailed images provided by CT scans may eliminate the need for exploratory surgery.
