Before your positron emission tomography (PET) scan, a technologist will insert a small intravenous (IV) line into your arm. The technologist will inject a small amount of a radioactive tracer called FDG into your IV line. Once you’ve received your injection, you’ll rest quietly for 30 to 60 minutes to allow the FDG to distribute in your body.
Next, the technologist will ask you to lie on the PET scanner table, which will slowly pass through the PET scanner. The PET scanner detects and records the signals the tracer substance emits. A computer reassembles these signals into images.
In some cases, your doctor may request a second injection of IV contrast material so we can better see inside your body. If you need it, you’ll receive this second injection during your scan.

Every PET scan is different, but most take about 30 to 45 minutes.
You will go over the results of your PET scan with your doctor.
