An ultrafast computed tomography (CT) scan is an imaging test that uses X-rays and a computer to look at your child’s heart. The scan takes pictures very quickly. It gives the healthcare provider many details about your child’s heart that other imaging tests can’t.
Standard X-rays use a small amount of radiation to create images of bones and organs. These X-rays are useful to help diagnose illness. But many details about internal organs and other structures can’t be seen.
With a CT scan, the X-rays move around the body. This gives many views of the same organ or structure in much greater detail. The X-ray information is sent to a computer. The computer makes a 2-D image that your healthcare provider can look at. IV contrast dye may also be used to make details show up better in the scan.
An ultrafast CT scan shows the healthcare provider even more details about the heart’s structure and how well it is working. It also can be done in much less time than a regular CT scan.

A CT scan is done by a radiology technologist. A radiologist is on call in case of problems. This is a doctor trained to use CT or other imaging methods to test or treat patients.
During the test:
Once the test is finished, the table will slide out of the scanner. A child who received medicine to relax or sleep will be watched until the medicine wears off and he or she is awake again. If an IV was inserted, it will be taken out after the test is over and your child is awake.
If no sedation was used, your child can go back to normal activities and diet right away, unless the healthcare provider says otherwise. Contrast dye should pass through your child’s body in about 24 hours. Your child may need to drink more water during this time.
If your child had sedation, he or she may feel sleepy for a while. This should go away in a few hours or a day.
Your child’s healthcare provider will talk with you about the results of the CT scan, and let you know if other tests are needed.
