PET/CT

CCCNF is the first facility in Northern Florida to incorporate PET/CT technology to more precisely diagnose tumor spread. Both our Lake City and Gainesville offices have PET/CT scanners on site.

What is a PET/CT scan?

An integrated PET/CT scan is the most advanced imaging technology for the detection and evaluation of cancer. The whole-body scan generates high resolution images of abnormal activity and its location.

Abnormal biological activity often takes place before physical changes are identifiable by other imaging exams such as MRI, CT, x-ray and ultrasound. A PET/CT scan provides images of the entire body, detecting primary and secondary disease earlier and more accurately than other imaging technology.

What are the benefits of a PET/CT scan?

  • PET/CT replaces multiple medical testing procedures with a single exam.
  • PET/CT identifies disease often before it shows up on other exams.
  • PET/CT scans the whole body so it can indicate whether or not the cancer has spread.
  • PET/CT shows the progress of disease and how the body responds to treatment.
  • PET/CT reduces or eliminates ineffective or unnecessary surgical or medical treatments.

Physicians use PET/CT images to determine the extent of disease and the effectiveness of chemotherapy, radiation therapy or surgery. PET/CT scanning allows early detection of the recurrence of cancer, revealing tumors that might otherwise be obscured by scar tissue which can result from surgery and radiation therapy.

How is the PET/CT scan conducted?

A small amount of radioactive sugar is injected into a patient’s bloodstream. The radioactive sugar circulates in the body while the patient relaxes for approximately one hour. The patient is then positioned on a bed that slowly passes through the scanner. The PET/CT scan takes approximately 30 minutes.

Is a PET/CT scan safe?

Yes. The risks associated with PET/CT scanning are minimal. Radioactive sugar, also known as glucose, is short-lived and leaves the body quickly. The radioactive sugar is not a contrast agent. The radiation exposure associated with a PET/CT scan is similar to that associated with conventional imaging exams.

How should you prepare for a PET/CT scan?

  • DO NOT EAT or DRINK anything 6 hours prior to your PET/CT scan (including candy, coffee, chewing gum, cough drops, or mints).
  • Drink at least 6 glasses of water during the 24 hours prior to your appointment.
  • Most medications are acceptable.
  • Do not perform strenuous activity 24 hours before your scan (e.g., weight lifting, running, aerobics).
  • Please wear warm, comfortable, metal-free clothing to your appointment.
  • Tobacco Users - Do not smoke or use tobacco for at least 12 hours prior to your exam.
  • If you currently have or have had a recent infection, please call our office before your scan.
  • If you are diabetic or extremely claustrophobic, please call our office before your scan.
  • Please arrive 15 minutes prior to your scheduled appointment time.
  • Please bring your current insurance card(s) and photo identification along with your copay/payment for service, as applicable.
