A CT scan is a diagnostic medical test that, like an X-ray, produces multiple images or pictures of the inside of the body. During a CT scan, the person is positioned on a table and then moved through a doughnut-shaped machine called a gantry. The gantry contains an X-ray tube that rotates around the body, taking many pictures. CT scans are painless and take only a few minutes. The person being scanned may be asked to hold their breath for short periods of time to avoid blurring the images.
Expect during your CT scan:
- You will lie on a table and the table will slide into the CT scanner. You will be asked to hold your breath for short periods of time while the scan is being done.
- The CT scanner takes x-rays from different angles and produces detailed images of your body.
- CT scans are painless and usually take about 30 minutes.
- You may be asked to drink contrast liquid before the scan. This liquid helps produce clearer images. You may also be asked to hold your breath for short periods of time during the scan.
