Computed tomography (CT) is a type of imaging. It uses special x-ray equipment to make cross-sectional pictures of your body.
Doctors use CT scans to look for:
- Broken bones
- Blood clots
- Signs of heart disease
- Internal bleeding
During a CT scan, you lie still on a table. The table slowly passes through the center of a large X-ray machine. The test is painless. During some tests you receive a contrast dye, which makes parts of your body show up better in the image.
