PET scans can show solid tumors in the brain, prostate, thyroid, lungs, and cervix. The scans can also evaluate the occurrence of colorectal, lymphoma, melanoma, and pancreatic tumors. They are also used to assess if treatment is being effective in eliminating cancer.

What is injected during a PET scan?

Before your PET-CT scan, you will get an injection of a small amount of a radioactive sugar called fluorodeoxyglucose-18. This substance is sometimes called FGD-18, radioactive glucose, or a tracer. The cells in your body absorb sugar. Areas that use more energy pick up more of the sugar.

Why is my doctor recommending a PET scan?

– Lung cancer – Lymphoma – Colorectal cancer – Melanoma – Head and neck cancer – Breast cancer

What is a PET scan and what does it do?

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 (tracer) to show both normal and abnormal metabolic activity. A PET scan can often detect the abnormal metabolism of the tracer in diseases before the disease shows up on other imaging tests, such as computerized tomography (CT) and magnetic resonance imaging (MRI).

What is better a MRI or a PET scan?

There is no radiation hazard risk for the patients undergoing an MRI scan. A PET scan, on the other hand, is a procedure with a certain level of radiation involved. The levels of radiation received by patients during a PET scan are comparable with the level of radiation received during a X-ray procedure.
