WHAT IS A PET/CT SCAN?

A PET/CT Scan is a diagnostic tool using both Positron Emission Tomography, or P.E.T and CT technology to provide both metabolic (functional) information and anatomical information, respectively about the body. To create these images compounds like simple sugars (glucose, for example) are labeled with radioactive signal-emitting tracers which are injected into the patient. A scanning machine records the signals these tracers emit as they journey through the human body and collect in various amounts in normal versus diseased or inflamed tissue.  A computer reassembles the signals into images, resulting in pictures, which show normal functioning organs and tissues as well as sites of acute inflammation, infection, or cancer.  P.E.T. is also being used in the early diagnosis of Alzheimer’s disease.

 

HOW IS A PET SCAN PERFORMED?

A very small amount of radioactive labeled glucose (FDG) is infused via an IV line started in your arm. You should not feel any side affects from the material. Most of the radioactivity will be gone by the time you leave the department. After receiving the injection you will relax in an easy chair for approximately 45 minutes while the FDG travels through your body. You will then be placed on a scanning table (One that resembles a CT Scan) for about an hour. It is extremely important to lie still throughout the exam.

How DO I Prepare for a PET Scan?

Please refer to the following patient form for PET/CT preparation instructions
(P.E.T. Scan Form).

PLEASE BRING ANY PRIOR CT or MRI (CD or Film) with you for comparison purposes, if they were not performed at North Fork Radiology, or one of our other sites listed in the locations page.

NEW State of the Art Imaging for Dementia and Alzheimer’s Disease

North Fork radiology offers the latest State of the Art Imaging for Dementia and Alzheimer’s disease. We offer conventional brain PET/CT scanning and the newest imaging technique for Alzheimer's disease that uses a new imaging product called Amyvid, which can detect the amount of Amyloid plaque deposition in the brain which is a hallmark characteristic of Alzheimer's disease. In addition to these tests we offer state of the art MRI and CT imaging. North Fork radiology has board certified neuroradiologists and PET/CT accreditation by the American College of Radiology.


NEW pET/CT NaF Bone Imaging

North Fork Radiology is excited to introduce PET/CT imaging using Sodium Fluoride (F18-NaF) which recent studies have shown to be a superior imaging agent in the diagnosis of bone metastasis (in comparison to standard nuclear medicine bone scans).
