Do PET Scans Hurt?
A PET scan, or positron emission tomography scan, is a medical imaging technique that uses a small amount of radioactive material to create images of the body's internal organs and tissues. It is often used to diagnose and monitor cancer, heart disease, and other conditions.
What to Expect During a PET Scan
Before the scan, you will be given a small amount of radioactive material to swallow or inject. This material will travel through your bloodstream and collect in the organs and tissues that you are being scanned.
You will then be placed on a table that moves slowly through a large scanning machine. The machine will detect the radioactive material and create images of your body.
The scan usually takes about 30 minutes, but it may take longer depending on the area of your body being scanned.
Do PET Scans Hurt?
PET scans are generally painless. However, you may feel a slight pinch when the radioactive material is injected.
Some people may also experience mild side effects from the radioactive material, such as nausea, vomiting, or headache. These side effects usually go away within a few hours.
Who Should Not Have a PET Scan?
PET scans are not recommended for pregnant or breastfeeding women because the radioactive material can harm the baby.
People with severe allergies or kidney problems may also need to avoid PET scans.
What are the Benefits of a PET Scan?
PET scans can provide valuable information about the body's internal organs and tissues.
This information can be used to diagnose and monitor a variety of conditions, including:
- Cancer
- Heart disease
- Brain disorders
- Infections
- Inflammation
What are the Risks of a PET Scan?
PET scans are generally considered safe. However, there are some potential risks associated with the procedure, including:
- Radiation exposure: The radioactive material used in PET scans can expose you to small amounts of radiation.
- Allergic reactions: Some people may experience allergic reactions to the radioactive material.
- Kidney problems: People with kidney problems may experience kidney damage from the radioactive material.
Talk to Your Doctor
If you are considering having a PET scan, talk to your doctor about the benefits and risks of the procedure. Your doctor can help you decide if a PET scan is right for you.
