Patient Safety

During a PET scan, you will be exposed to a small amount of radiation. The radioactive tracer that is used in the scan emits positrons, which are very small particles. These particles produce a type of radiation called gamma rays.

The amount of radiation you receive during a PET scan is considered safe, and it is similar to the radiation exposure you might receive from other medical imaging tests like a CT scan. The actual amount of radiation can vary depending on the specific procedure and the part of the body being scanned.

Radiation exposure is measured in a unit called millisieverts (mSv). On average, a PET scan can expose you to a radiation dose ranging from 2 to 10 mSv. To put this into perspective, the average person in the United States is exposed to about 3 mSv of radiation each year from natural sources, such as the sun and the Earth.

It’s important to note that medical professionals carefully control the amount of radiation you receive during a PET scan to keep it as low as possible while still getting the necessary images. They follow strict safety guidelines to ensure your well-being.

If you have any concerns or questions about radiation exposure during a PET scan, it’s always a good idea to discuss them with your doctor. They can provide you with more specific information based on your individual situation.
