A PET scan is a type of medical imaging that uses small amounts of radioactive material to create images of the body. The radioactive material is injected into the body, and it travels to the organs and tissues being studied. A special camera detects the radioactivity and creates images of the organs and tissues.

Do Pet Scans Have Radiation?

What is the radiation dose from a PET scan?

The radiation dose from a PET scan is typically very low. The average effective dose from a PET scan is about 0.02 millisieverts (mSv).

This is equivalent to the amount of radiation you would receive from about 2 chest X-rays.

Is the radiation from a PET scan harmful?

The radiation dose from a PET scan is very low, and it is unlikely to cause any harm. However, there is a small risk of developing cancer from any exposure to radiation, including the radiation from a PET scan.

The risk of cancer from a PET scan is very small, but it is important to be aware of it. If you are concerned about the radiation from a PET scan, talk to your doctor.

When is a PET scan used?

A PET scan is used to diagnose and monitor a variety of conditions, including:

  • Cancer
  • Heart disease
  • Brain disorders
  • Infections
  • Other medical conditions

What are the risks of a PET scan?

A PET scan is a generally safe procedure, but there are some risks involved, including:

  • Radiation exposure: The radiation dose from a PET scan is very low, but there is a small risk of developing cancer from any exposure to radiation.
  • Allergic reaction: Some people may have an allergic reaction to the radioactive material used in a PET scan.
  • Kidney damage: The radioactive material used in a PET scan can damage the kidneys if it is not properly eliminated from the body.
  • Other side effects: Some people may experience side effects from a PET scan, such as nausea, vomiting, and headache.
