Can a PET Scan Make You Sick?

A PET (Positron Emission Tomography) scan is generally a safe medical imaging procedure that does not make most individuals sick. However, there are a few considerations to keep in mind:

  1. Radiation Exposure: PET scans involve the use of a small amount of radioactive material (known as a radiotracer) to produce images of the body’s internal processes. The radiation exposure from a PET scan is typically low and is considered safe for most patients. However, if you have concerns about radiation exposure or are pregnant or breastfeeding, it’s essential to discuss these concerns with your healthcare provider.
  2. Side Effects: In some cases, patients may experience mild side effects related to the radiotracer, such as:
    • Allergic Reaction: While rare, some individuals may have an allergic reaction to the radiotracer. Symptoms can include itching, rash, or hives. In very rare cases, a severe allergic reaction known as anaphylaxis can occur.
    • Nausea: Some patients may experience mild nausea after the injection of the radiotracer. This is not common and typically subsides quickly.
    • Discomfort at the Injection Site: The injection of the radiotracer can cause temporary discomfort or pain at the injection site.
  3. Preparation and Fasting: To ensure the accuracy of the PET scan, patients are often required to fast for a period before the procedure. While fasting can be uncomfortable, it is a necessary part of the preparation.
  4. Claustrophobia: PET scans involve lying still in a confined space during the imaging process. Some individuals with claustrophobia may experience discomfort or anxiety during the scan.

It’s important to discuss any concerns or potential side effects with your healthcare provider before undergoing a PET scan. They can provide guidance on the preparation and address any specific medical considerations.

In summary, a PET scan is generally well-tolerated, and most patients do not become sick from the procedure. Any side effects or discomfort are typically mild and temporary. Patients with concerns about radiation exposure, allergies, or other medical conditions should communicate these concerns with their healthcare team to ensure a safe and effective imaging experience.
