What is a positron emission tomography (PET) scan?

ANSWER

This scan uses small amount of radioactive material known as a tracer injected into a vein. The tracer triggers a reaction between positively and negatively charged particles to make an image. Your doctor can look at an organ from every angle and detect potential problems.

It’s important to tell you doctor if you may be pregnant, since the PET scan can be harmful to an unborn child.
