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 any 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 evaluates all the organ systems of the body in a single exam, so it can indicate whether or not the cancer has spread.
- PET/CT shows the changes in disease and how the body responds to treatment.
- PET/CT reduces or eliminates ineffective or unnecessary surgical or medical treatments.
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.
