How Often Should A Pet Scan Be Repeated
PET scans are a relatively new technology that can help doctors detect cancer cells, inflammation and brain damage. If you’ve had a PET scan, you may be wondering when you should do it again.
PET scans help doctors detect cancer cells, inflammation and brain damage. If you’ve had a PET scan, you may be wondering when you should do it again.
Depending on the reason you had your PET scan, the scan may be repeated every few months or yearly.
A PET scan is typically used to detect cancer in its early stages. The more often you have a PET scan done, the higher chance of detecting a cancer at an earlier stage. However, there’s also a risk of false positives and false negatives with multiple scans as well as high costs for these tests. If your doctor believes there’s no need for further testing after one or two years post-treatment, it might be best to wait until symptoms appear before getting another PET scan done again.
How Often Should a PET Scan Be Repeated?
A PET scan may be repeated to determine if a tumor has disappeared or spread. Your doctor will recommend the frequency of your repeat scan based on your individual circumstances and the results of previous scans. The following factors can help determine how often a PET scan should be repeated:
- Results of other tests (e.g., CT, MRI, X-rays). In some cases, it may not be necessary to do another PET scan right away after an initial one because you have had other tests that are more accurate and reliable than a PET scan in determining whether there is cancer in your body.
- Treatment response. If you have been undergoing treatment for cancer, you might need to have another PET scan sooner than someone who has not started any treatment yet. This will help doctors monitor how well their treatments are working by comparing images taken before and after they begin treatment so they can see if there is any change in the size or location where tumors were found before starting treatment compared with where they appear afterward.”
The exact time depends on what’s happening with your health. According to Cleveland Clinic’s US News & World Report, repeating a PET scan is generally done when something has changed since the last one. This can include symptoms getting worse or side effects from other types of treatment starting to show up.

If you’re concerned about having another PET scan too soon, talk with your doctor about whether it’s really necessary and when you’ll need another one based on the results of your previous tests. Your physician may be able to provide information regarding how often other people who are in similar situations have had theirs repeated, which can give you some guidance as well.
Your doctor might also want to repeat the scan right after your first test if they need to compare it with something else, like another scan or a lab test.

If you had surgery or a biopsy, you may need a follow-up scan to see if the treatment worked. If you have symptoms that haven’t gone away, your doctor may want to check again to see if they’re getting worse. If there’s no change in how your thyroid looks on PET/CT scans over time, then it’s possible that it isn’t hyperactive anymore and doesn’t need treatment.
What Is the Difference Between a PET Scan and an MRI?
A PET scan is a noninvasive imaging technique that can detect abnormalities in the brain and body. It looks at how much sugar your cells use to function — known as metabolism — by measuring glucose levels in your body.
A magnetic resonance imaging (MRI) scan uses a magnet to create cross-sectional images of your body’s organs and tissues. It can show structures inside the body such as bones, muscles, tendons, ligaments and nerves.
According to Medical News Today, a PET scan provides more detailed information about your body than an MRI does. An MRI is better at showing structures inside the body and can show more detail, but it may not be able to detect function or abnormalities in certain organs like a PET does. Some people need both scans for different reasons, but both tests are noninvasive and should feel similar for the patient. What happens during the actual test can vary between different medical practices.

The best way to find out if you need a PET scan is by asking your doctor what they think you might benefit from most. They’ll help you determine whether or not you should have one done and when they think it will be appropriate to do so. They should also give you some examples of when this type of test could be useful for diagnosing or monitoring conditions like cancerous tumors or cardiovascular disease risk factors such as obesity, hypertension (high blood pressure), diabetes mellitus type 2; metabolic syndrome etcetera.”
Tips for Getting Ready for Your Test
- Make sure to have someone to take you to and from the test.
- Bring your insurance information with you, including the name of the plan and ID number.
