Is A Pet Scan Radiation
Introduction
A positron emission tomography (PET) scan is an imaging test that allows your doctor to check for diseases in your body. The scan uses a radioactive drug, or tracer, to show this activity. This scan can sometimes detect disease before it shows up on other imaging tests. A PET scan is different from an MRI or CT scan. Those scans create pictures of areas inside the body. But they don’t show cellular activity, which PET scans can reveal. A standard PET scan takes about 30 minutes to complete and doesn’t require you to stay in a hospital overnight because it uses low doses of radiation.
PET scans use a radioactive drug called a tracer to look for disease in the body.
A PET scan is a type of imaging test that uses radioactive tracers to look for disease in the body. Tracers are either swallowed, inhaled, or injected into your arm, depending on the type of PET scan you’re having.
The tracer will then collect around active cancers and tumors as they are functioning. The more cancer cells there are in your body and the faster they grow, the brighter those areas will appear on the scan.
The tracer is either swallowed, inhaled, or injected into your arm, depending on the type of PET scan you’re having.
- The tracer is either swallowed, inhaled, or injected into your arm depending on the type of PET scan you’re having.
- If your doctor gives you the option to take an injection before the test, he or she probably has a good reason for doing so. Always ask about this beforehand so that it doesn’t come as a surprise during your exam.
The tracer travels through your body and gives off energy in the form of gamma rays, which are detected by a special camera and a computer to create images of the inside of your body.
A PET scan is a special type of test that uses small amounts of radioactive material (tracers) to find out how your body works and if there is anything wrong with it. The tracer travels through your body and gives off energy in the form of gamma rays, which are detected by a special camera and a computer to create images of the inside of your body.
The tracer is usually injected into the vein using an IV. Some patients may receive their medication through an injection below their skin or into their muscle.
The FDA has approved several different forms of the drug.

It’s important to know that although you won’t experience any side effects from taking this clinical trial drug (so long as you’re not pregnant), it can cause some mild discomfort during the injection process. Some people report feeling a little nauseous at first and others say they feel lightheaded when receiving their dose—but these symptoms usually go away within an hour after injection and aren’t serious enough to warrant calling an ambulance or anything like that!
PET scans can help you find out if you have cancer and how far it has spread.
PET scans can help find cancer, the stage of cancer and how far the cancer has spread. They can also show if treatment is working for you. They are useful for finding out about many different types of cancers including:
- Lung cancer
- Breast cancer
- Brain tumors (primary or metastatic)
- Prostate cancer
Conclusion
There are a few things to keep in mind when you get your results: PET scans can show areas of your body where cells are using more glucose than normal, but they don’t always mean cancer is present. A tissue sample (biopsy) is needed for a definite diagnosis.
The amount of radioactivity used in most PET scans is low, so the risks from radiation exposure are minimal.
