A positron emission tomography (PET) scan is an imaging test that can help reveal the metabolic or biochemical function of your tissues and organs. The PET scan uses a radioactive drug called a tracer to show both typical and atypical metabolic activity. A PETscan can often detect the atypical metabolism of the tracer in diseases before the disease...
A PETscan is an effective way to help discover a variety of conditions, including cancer, heart disease and brain disorders. Your health care provider can use this information to help diagnose, monitor or treat your condition.
For your PETscan, a radioactive drug called a tracer will be injected into a vein. Because the amount of radiation you're exposed to in the tracer is small, the risk of negative effects from the radiation is low. But the tracer might: 1. Expose your unborn baby to radiation if you are pregnant. 2. Expose your child to radiation if you are breastfee...
Tell your health care provider: 1. If you've ever had a bad allergic reaction. 2. If you've been sick recently or you have another medical condition, such as diabetes. 3. If you're taking any medicines, vitamins or herbal supplements. 4. If you're pregnant or you think you might be pregnant. 5. If you're breastfeeding. 6. If you're afraid of enclos...
The PET-CT or PET-MRI scanner is a large machine that looks a little like a giant doughnut standing upright, similar to CT or MRIscanners. From start to finish, the procedure takes about two hours to complete and typically does not require an overnight hospital stay. When you arrive for your scan, you may be asked to: 1. Change into a hospital gown...
A specialist trained to interpret scan images, called a radiologist, will report the findings to your provider. The radiologist may compare your PET images with images from other tests you've undergone recently, such as an MRI or CT. Or the PETimages may be combined to provide more detail about your condition.

A PET scan uses a radioactive tracer to show the metabolic activity of your tissues and organs. It can help detect, stage and monitor cancer, as well as other conditions such as heart disease and brain disorders.
Oct 19, 2022 · A PET scan is an imaging test that uses a radioactive tracer to show how your organs and tissues are functioning. It can help diagnose and monitor cancer, heart and brain conditions. Learn how to prepare, what to expect and what the results mean.
Learn how a PET-CT scan can help find and stage cancer, and how to prepare for this type of imaging test. A PET-CT scan combines a positron emission tomography (PET) scan with a computed tomography (CT) scan to show abnormal activity and structure in the body.
Apr 27, 2015 · Learn what a PET scan is, how to prepare for it and what to expect during and after the test. A PET scan uses a radiotracer to measure how your tissues and organs are functioning and can help diagnose or monitor cancer.
Oct 29, 2021 · A PET/CT scan is a nuclear imaging technique that combines a PET scan and a CT scan to show the structure and function of cells and tissues in the body.
