The risk from having a CT angiogram is small. But
some risks include:
- Exposure to radiation. There is a slight chance
of developing cancer from some types of CT scans.1 The
chance is higher in children, young women, and 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. Make sure that the
test is needed.
allergic reaction to the dye (contrast material). But
this is rare, and most reactions are mild and can be treated with medicine.
- Kidney problems. The dye used during the test can cause kidney
damage in people whose kidneys don't work well.
The dye may also cause problems for people who take
metformin (such as Glucophage) to control their diabetes. Your doctor will tell
you when to stop taking metformin and when to start taking it again after the
test so you won't have a problem.
