PET/CT Scans for Accurate Diagnoses

High Tech Imaging for Cancer and Other Conditions

A PET/CT can depict both technologies using a single machine. It provides a picture of function (PET), a picture of anatomy (CT) and a merged picture of both the body’s metabolism and structure.

PET/CT helps physicians diagnose, stage and treat cancer with more accuracy than ever before. The exam can:

  • Provide answers to critical questions
  • Improve diagnostic confidence for patients who have, or may have, cancer.
  • Reduce the need for invasive procedures like biopsy or surgery.
  • Help avoid the “wait and see” method, often used to monitor potential disease.
  • Monitor patients’ response to treatment to ensure the treatment is working.

What to expect

During the exam: You will receive a small injection of FDG (sugar water with a radioactive tracer). You will sit or lie down on a comfortable chair or bed for 30-90 minutes while the FDG travels throughout your body.

After this time, the technologist will assist you to the scanner. The CT portion of the exam is completed first, followed by the PET portion. You may be asked to hold your breath for several seconds while the CT scan is performed.

After the exam: Once the total scan has been performed, you may resume daily activity. Even though the FDG will quickly leave your body, you can expedite the process by drinking plenty of water after your scan is complete.
