Computed tomography

Computed tomography, also known as CT or CAT scan, is a medical imaging technique that uses X-rays and computer technology to produce detailed, cross-sectional images of the body.

Uses

These images provide detailed information about the internal organs, bones, and tissues, allowing for accurate diagnosis and treatment planning.

Procedure

The procedure involves the patient lying on a table that moves through a donut-shaped machine, during which multiple X-ray images are taken from different angles.

3-D images

A computer then combines these images to create detailed, three-dimensional images of the internal structure of the body.

Application in medicine

• CT scans are used for a variety of medical conditions, including tumors, injuries, and infections.
• It can be used for both diagnosis and treatment plan, because it gives detail and more specific area than Xray.

Risks

• It also carries slight higher radiation risk than X-ray.
