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.
- Prior the PET/CT you will be asked to empty your bladder.
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.
