Getting the Results
The CAT scan images will be looked at by a radiologist (a doctor specially trained in reading and interpreting X-ray images). The radiologist will send a report to your doctor, who will discuss the results with you and explain what they mean.
Results are usually ready in 1-2 days. If the CAT scan was done on an emergency basis, the results can be made available quickly. In most cases, results can't be given directly to the patient or family at the time of the test.
Risks
In general, CAT scans are very safe, although more radiation is required than in a regular X-ray. Any exposure to radiation poses some risk to the body, but the amount used in an individual CAT scan isn't considered dangerous. It's important to know that radiologists use the minimum amount of radiation required to get the best results.
If your daughter is pregnant, there's a risk of harm to the developing baby, so precautions must be taken.
Contrast solutions are generally safe, with a very low incidence of allergic reactions. Talk with your doctor if you have any concerns about a possible allergy. Make sure to tell your doctor about any medication, dye, and food allergies that your child may have. Some patients who are at risk for allergic reaction to the contrast solution may need medications like antihistamines or steroids to minimize the risk of adverse reaction.
If your child requires sedation, there's a slight chance of slowed breathing due to the medications. If there are any problems with the sedation, the CAT scan staff is prepared to treat them right away.
Helping Your Child
You can help your child prepare for a CAT scan by explaining the test in simple terms before the procedure. You can describe the room and the equipment that will be used, and reassure your child that you'll be close by. For older kids, be sure to explain the importance of keeping still so the scan can be completed quickly and parts of it don't have to be repeated.
If You Have Questions
If you have questions about why the head CAT scan is needed, speak with your doctor. You also can talk to the CAT scan technician before the procedure.
