How To Take Care After Your PET Scan: How Long Should You Isolate Yourself?

Have you recently undergone a PET scan and are wondering what the aftercare procedure entails? Are you worried about how long you need to stay away from people, if at all? In this article, we’ll break down the necessary precautions to be taken after a PET scan and how long should one isolate themselves to prevent any potential harm. Read on to learn more!

Introduction to PET Scans

A PET scan is a type of imaging test that uses special cameras and computers to create pictures of organs and tissues inside your body. The full name for this test is positron emission tomography.

PET scans are used to check for many different conditions, including cancer, heart problems, and brain disorders. They can also be used to see how well certain treatments are working.

If you’re going to have a PET scan, you’ll likely be told to avoid eating or drinking anything for at least 4 hours beforehand. That’s because food or drink can cause the images to be blurry.

You may also be asked to wear loose-fitting clothing so that the camera can get a clear view of your body. And you may be asked to remove any jewelry or metal objects that could interfere with the scan.

Once you’re ready for the scan, you’ll lie on a table in the middle of the PET scanner. The scanner is large and round, like a doughnut. You’ll need to stay still during the test, which usually takes about 30 minutes.

What is the Procedure?

If you’re like most people, you probably have lots of questions about your PET scan. Here’s what you can expect before, during, and after the procedure.

Before your PET scan, you’ll be asked to fill out a medical history form. This is so the technologist can check for any medical conditions that could affect the test.

You’ll also be asked to remove any jewelry or other objects that may interfere with the scan. You’ll then be given a hospital gown to wear during the procedure.

During the PET scan, you’ll lie on a table while a camera moves around you. The camera sends images to a computer, which creates a 3-dimensional image of your body.

The whole process takes about 30 minutes. You may be asked to hold your breath for short periods of time during the scan.

After the PET scan, you can go back to your normal activities right away. There are no side effects from the procedure itself.

How Long Should You Isolate Yourself?

If you have recently had a PET scan, you may be wondering how long you should isolate yourself afterward. The answer to this question depends on a few factors, including the type of PET scan you had and your doctor’s recommendations.

If you had a whole-body PET scan, it is important to follow your doctor’s instructions carefully. You will likely be asked to stay in a hospital room for at least four hours after the procedure so that the radiopharmaceutical can decay. Once you are released from the hospital, you should avoid close contact with others for at least 24 hours. This means no hugging, kissing, or shaking hands. You should also avoid pregnant women, small children, and people with compromised immune systems.

If you had a partial-body PET scan, you will not need to stay in the hospital after the procedure. However, you should still avoid close contact with others for at least four hours afterward. This is because the radiopharmaceutical used in partial-body PET scans has a shorter half-life than the one used in whole-body scans.

It is important to follow your doctor’s instructions carefully after having a PET scan. By doing so, you can help ensure that your radiation exposure is minimized and that you do not put others at risk of exposure.

Safety Protocols During and After a PET Scan

After your PET scan, you will need to follow some safety protocols to protect yourself and others. You will be radioactive for a short time after the scan, so it is important to avoid close contact with other people. You should also avoid touching anything that might be contaminated with radiation, such as doorknobs or countertops. It is also important to drink plenty of fluids and urinate often to help flush the radiation out of your body.

Common Questions Regarding Isolation Requirements After a PET Scan

After a PET scan, it is important to follow your doctor’s instructions for isolation. Depending on the type of radioisotope used, you may be asked to stay in your room, avoid contact with other people, or take other precautions. Here are some common questions patients have about isolation requirements after a PET scan:

How long do I need to stay in my room after the PET scan?
The length of time you need to stay in your room depends on the type of radioisotope used. For example, if you had an FDG PET scan, you would need to stay in your room for 6 hours. However, if you had a NaF-18 PET scan, you would only need to stay in your room for 1 hour.

What are the restrictions on visitors after a PET scan?
Visitors are usually not allowed in the scanning suite during scans. After the scan, depending on the type of radioisotope used, you may be asked to avoid close contact with other people (such as hugging or kissing). You should also avoid sharing food or drinks with others.

Can I go home after my PET scan?
Most patients can go home after their PET scan. Patients who have received certain types of radioisotopes (such as FDG) may be asked to wait a short period of time before leaving so that they can reduce their radiation exposure to others.

Alternatives to Isolation After a PET Scan

If your healthcare provider has recommended that you isolate yourself after your PET scan, there are a few alternatives that may be right for you. If you are healthy and have no symptoms of infection, you may choose to stay in contact with others outside of your immediate family while taking precautions to avoid spreading any illness. This includes maintaining a distance of at least six feet from others, avoiding close contact with anyone who is sick, washing your hands often, and limiting travel outside of your home as much as possible. If you are not comfortable with these risks, or if you have any symptoms of an infection, it is best to follow the health care provider’s recommendation to isolate yourself until the risk of transmission has passed.


Taking care of yourself after a PET scan is an extremely important part of the process. It’s important to remember that each case is different, so you should follow your doctor’s instructions regarding how long you should isolate yourself and other precautions to take. That being said, most people can go back to their regular activities within 24 hours of the test. Keeping track of any side effects and following up with your healthcare provider if necessary can help ensure that you get a safe and successful test experience with minimal disruption to your everyday life.
