FDG PET is a type of medical imaging test that uses a radioactive tracer to help doctors detect and monitor cancer. The tracer, called fluorodeoxyglucose (FDG), is a sugar molecule that is taken up by cells in the body. Cancer cells, which are more metabolically active than normal cells, take up more FDG than healthy cells.

What is FDG PET?

How is FDG PET Performed?

1. Preparation:

Before the test, you will receive a small amount of FDG through an intravenous line in your arm. You will then need to wait for about 60 to 90 minutes while the FDG circulates through your body and is taken up by your cells.

2. Imaging:

Once the FDG has had time to circulate, you will lie down on a table inside a PET scanner. The scanner will rotate around you, detecting the gamma rays emitted by the FDG in your body. A computer will then use this information to create images of your organs and tissues.

What are the Uses of FDG PET?

FDG PET is used to diagnose and monitor a variety of different types of cancer, including:

1. Breast cancer

2. Lung cancer

3. Colorectal cancer

4. Lymphoma

5. Melanoma

FDG PET can also be used to:

1. Determine the stage of a cancer

2. Evaluate the effectiveness of cancer treatment

3. Detect recurrence of cancer after treatment

Are There Any Risks or Side Effects of FDG PET?

FDG PET is a generally safe procedure. However, there are a few potential risks and side effects, including:

1. Radiation exposure:

FDG PET involves the use of a radioactive tracer, which exposes you to a small amount of radiation.

2. Allergic reaction:

Some people may experience an allergic reaction to the FDG tracer.

3. Injection site pain:

You may experience some pain or discomfort at the injection site where the FDG was administered.
