PET/CT is a state-of-the-art technique that combines Positron Emission
Tomography (PET) with Computed Tomography (CT) to image tissue
and organ function. Our GE scanner is the most advanced and accurate
PET/CT scanner available anywhere. This scan is designed to accurately
identify even small areas of abnormal metabolic activity, which
are associated with several disease processes. PET/CT’s major
clinical impact to date is in cancer diagnosis and staging; however,
PET/CT is also a useful modality for imaging the heart and brain.
PET/CT can show more than just where tumors are located. PET/CT
can reveal whether lesions are benign or malignant and can assess
the effectiveness of treatment, whether surgery, chemotherapy,
or radiation therapy.
When you arrive at Princeton Radiology’s Nuclear Imaging
Suite, a technologist will discuss the PET/CT procedure with you
and ask if you have any questions. When you are ready for your
PET/CT scan, you will have your blood sugar tested. Next, most
patients will receive an oral contrast (barium drink). An IV will
then be started, and you will receive an injection of a small amount
of safe, radioactive sugar. You will not experience any side effects
from this material. You will then be asked to wait very quietly
in a seated area. Any activity, even talking or gum chewing, may
affect the results of your test. Prior to the scan, you will be
asked to empty your bladder.
You will lie on a bed that passes slowly through the scanner.
For scanning purposes, it is important that you lie quietly and
remain still on the bed during your scan. The length of time between
scans can vary depending on the body areas being studied, typically
between 30 to 60 minutes. You should plan to spend approximately
three hours total time at the Nuclear Imaging Suite for the entire
