PET/CT (Positron Emission / Computed Tomography)

PET/CT represents the next level of diagnostic imaging power for oncology. PET directs metabolic signals in the body while CT provides a detailed picture of the internal anatomy, revealing the location, size and shape of cellular activity. Alone, each imaging test is effective for a wide variety of applications. But when the results of PET and CT scans are "fused" together, the combined image provides more complete information on cancer location and metabolism.

What are the patient benefits realized through the use of PET/CT?

Detailed diagnostic information, early detection of disease, better monitoring of cancer recurrence, effective tracking and lower cost of care are all factors in the combination of both procedures.

What are the clinical applications of PET/CT ?

  • Oncology - possible cancer detection
  • Cardiology - possible heart disease detection
  • Neurology - brain imaging

How long does the exam take and does it hurt?

In most cases you will be on the scanner table for less than an hour. The scan itself causes no pain. Because the gantry is open, you will be able to see and speak with the technologist. An IV line could be started in your hand or arm in order to infuse a radiopharmaceutical.

What is being injected for the scan and why ?

For PET scans, a very small amount of a radiopharmaceutical is infused into the bloodstream. For a PET/CT scan you may also receive a contrast agent by mouth or intravenously (IV).

How do I prepare for the exam?

1. Arrive 30 MINUTES PRIOR to your PET exam, otherwise the exam my need to be rescheduled do to low dose of medication.
2. Please drink at least 5-6 glasses of WATER prior to exam to be well-hydrated.
3. Nothing to eat or drink except water and oral medications for at least 6 hours prior to injection. NO sweetened drinks.
4. Patients can take oral medications.
5. Patients on insulin should not take insulin at least 4 hours prior to injection.
6. Be sure to inform technologist if you are pregnant.
7. No vigorous exercise the day prior to exam.
8. No excessive talking or movement after injection.

What happens during the exam?

After the injection and during the scan, we ask that you are in a quiet resting state. It is extremely important that you lie still throughout the scan.

What happens after the scan?

It is important that you drink as much water as possible for the rest of the day and empty your bladder as often as possible. This will result in a more rapid clearance of radioactivity from your body. You can drive and resume normal activities immediately after leaving the facility.

When will I get the final results?

The final results will be given to your referring physician as soon as the images are analyzed, within 2 working days.

Will my insurance cover the exam?

Many insurance companies are reimbursing for some PET procedures, including Medicare. Contact your insurance carrier for more information.
