1 ½ – 2 hours. A radioactive tracer is administered upon your arrival, followed by a one hour wait (uptake time). The length of the scan is approximately 15-30 minutes, depending upon your weight.

What is a PET/CT?

Positron Emission Tomography (PET), Computer Tomography (CT) is a unique imaging study that allows physicians to pinpoint the exact size and shape of diseased tissue. A PET scan utilizes a radioactive glucose isotope that targets malignant cells.

Following injection, the patient receives a whole body PET scan to reveal malignant lesions that may have been overlooked by conventional imaging (CT, MRI or X-ray). When PET/CT is performed, it integrates both technologies, making it possible to obtain anatomical and biological data. PET/CT increases accuracy in tumor detection.

What are the benefits of PET/CT over other types of x-rays?

PET provides increased information regarding function and potential malignancy within a lesion. CT provides a detailed location of the concerned area. This imaging modality can:

  • Improve treatment planning
  • Reduce biopsy sampling error
  • Alter surgical procedures
  • Assist in treatment and therapy direction
  • Save lives

During the resting time, can I read or talk on the phone? Can my family member join me?

We ask you to refrain from all activities, including talking, as this can alter the outcome of your study. Family members need to remain in our waiting room. You may bring your own CD player or I-Pod with you to your appointment.

What is the future for PET/CT imaging?

PET/CT imaging is currently one of the most effective technologies available in identifying coronary artery disease. Cardiac PET provides accuracy and the capacity to monitor patients and favor maximal patient outcome at minimal overall expense. PET has also been approved for early stage diagnosis of Alzheimer’s, Dementia and Neurodegenerative Diseases.
