The Cancer Center at Lake Manassas is one of the only facilities in the area to offer PET/CT imaging with a direct link to our radiation treatment planning computer. This technology allows more accurate and efficient treatment planning, as the images are immediately imported into the cancer center treatment planning system in a matter of minutes.

What is PET/CT Imaging?

PET/CT imaging combines two tests—a PET (positron emission tomography) scan and a CT (computed tomography) scan—to produce images that allow doctors to more precisely pinpoint where cancers are located and how far they have spread. This lets the doctors make more accurate treatment planning decisions, allowing for more precise and effective care.

For patients with head and neck cancers, PET/CT imaging can be especially helpful. Head and neck cancers tend to be challenging to treat with radiation, and PET/CT imaging helps improve treatment effectiveness while keeping side effects and complications to a minimum.

How does the PET/CT exam work?

Prior to the exam, you will receive a small injection of a radioactive sugar (FDG). You will then be asked to rest quietly for approximately 60 – 90 minutes while the FDG collects throughout your body.

After this time, the technologist will assist you to the scanner. The CT portion of the test is completed first, followed by the PET portion. It is important you do not move for the duration of the scan, which may take anywhere from 30-40 minutes.

Although the images only take 30-40 minutes, you can expect to be on site for 2-2½ hours.

When the scan is completed, the computers will produce images for the radiologists to review. Your PET/CT results will not be immediately available, but the reading physician will contact your referring physician to convey all pertinent information.
