Computed Tomography (CT) Scan Of The Head And Face: Risks
Content provided by Healthwise
Risks
The chance of a CT scan causing a problem is small.
- There is a chance of an allergic reaction to the dye (contrast material).
- If you have diabetes or take metformin (Glucophage), the dye may cause problems. Your doctor will tell you when to stop taking metformin and when to start taking it again after the test so you will not have problems.
- There is a slight chance of developing cancer from having tests that use radiation. The chance is higher in children or people who have many radiation tests. If you are concerned about this risk, talk to your doctor about the amount of radiation this test may give you or your child and confirm the test is needed.
