About the PET exam

Why should I have a PET/CT if I have already had a CT and/or MRI?

PET Imaging provides images that are different from those produced by other radiological tests, such as CT, MRI, x-ray, ultrasound and mammography. Those tests look at anatomical changes in both, that is size and shape. PET/CT produces powerful molecular images that show changes in the biological function of cells.

Is PET/CT safe, and how long does scan take?

PET/CT is safe. The quantity of radioactivity involved in PET/CT is minimal. The injection itself contains a small amount of radioactive glucose. Glucose; a sugar, is a substance common to the cellular function of the body. The PET/CT scan typically takes about 30 to 60 minutes, depending on which part of the body is imaged.

Are there any side effects of PET/CT?

You should feel fine after the scan. The glucose tracer produces no side effects.

Who orders the PET/CT scan?

Any physician involved in your care; primary or specialist, can order a PET/CT scan.

Suppose my doctor will not order a PET/CT scan?

Educate yourself with as much information about your disease as possible and treatment options available to you. Ask your doctor to speak with one of the PET/CT radiologists at PET Imaging to see if you could benefit from a PET/CT scan. Call 781-769-4000, ext. 2606.

Do I have to be a patient in the Steward Health Care System to have a PET/CT at one of your locations?

No, you do not have to be a patient in the Steward system, your scan results can easily be transferred to a doctor of your request.
