Radiology PET CT & CT SCAN


What is a PET/CT and how does it work?

Positron Emission Tomography/Computed Tomography (PET/CT) is a non-invasive diagnostic imaging procedure that uses a radioactive tracer tagged to a form of sugar used by cells in the body for energy. This radioactive “tracer”; a radionuclide or radioisotope, is injected by our PET/CT technologist and lights up areas of abnormally high uptake. These bright spots on the PET/CT indicate changes in cellular metabolism while offering detailed anatomical images.

How to prepare for your PET/CT.

  •  Do not eat at least 6 hours prior to your exam.
  •  Please arrive 30 minutes prior to your scheduled appointment to complete paperwork.
  •  For your comfort we advise you to wear loose fitting clothing without metal closures.
  • If you are diabetic, please advise our scheduling department as you will require a glucose serum blood test prior to your PET/CT.
  • You will be called into our PET/CT waiting room by the PET/CT technician. You will be injected with a radioactive tracer and asked to wait 1 hour in a private waiting room while the tracer distributes throughout your body.

What to expect during the PET/CT procedure?

  •  After allowing the tracer to distribute throughout your body a PET/CT technician will chaperone you to the PET/CT table.
  • Once placed comfortable on the table the technician will leave the room.
  • The table is open on both ends to eliminate any concerns about claustrophobia
  • A pane of glass will separate you and the PET/CT technician.
  • The PET/CT room is silent; the only sounds you will hear are instructions from the technician.
  • Please pay close attention to their instructions.
  • Remain as still as possible throughout the procedure to avoid distorting the images.
  • From start to finish the entire process takes approximately 3 hours.
  • The actual scanning time on the table is approximately 30 minutes.

When and how do I get the results of my PET/CT?

  • It will take approximately 24-48 hours for a radiologist to interpret your PET/CT.
  • Please schedule a follow-up appointment with your Physician for results.
