Tests and Procedures
Positron emission tomography scan
Risks
For your PET scan, a radioactive drug (tracer) will be injected into a vein. Because the amount of radiation you're exposed to in the tracer is small, the risk of negative effects from the radiation is low. But the tracer might:
- Expose your unborn baby to radiation if you are pregnant
- Expose your child to radiation if you are breastfeeding
- Cause an allergic reaction, although this is rare
Talk with your doctor about the benefits and risks of a PET scan.
