PET-CT

About PET/CT at Bayshore Community Hospital

What is a PET/CT?

PET (Positron Emission Tomography) and CT (Computed Tomography) are standard imaging tools physicians use to pinpoint disease in the body. PET/CT scans produce three-dimensional images showing detail of the function and structure of tissues and organs in the body using a small amount of radioactive material. The PET scan looks at the biological function of the body while the CT scan provides information such as size, shape, and location. 

Why has my physician recommended a PET/CT? 

PET/CT scans allow your physician to examine your entire body at once, providing a more complete picture. Using the two scans physicians can more accurately diagnose and make treatment recommendations for conditions and diseases such as cancer, heart disease, and brain disorder.

Common uses of the PET/CT in different fields: 

  • Oncology: to determine between benign and malignant tumors in suspicious areas, identify if cancer has spread to other parts of the body, monitor successful therapies, detect recurrent tumors, and assess tumor aggressiveness.
  • Cardiology: to determine what heart tissue is still alive following a suspected heart attack or to predict the success of an angioplasty (balloon) or bypass surgery.
  • Neurology: for dementia to detect signs of Alzheimer’s, for epilepsy to determine the precise location for surgery, and in Parkinson’s Disease to assist physicians in the diagnosis of movement disorders.

During the Scan 

Prior to your scan you will receive an intravenous injection of a minimal amount of radioactive tracer which takes approximately 45-60 minutes to move through your body. During this time you will be asked to rest in a comfortable chair or bed. Once the tracer has been distributed you will be asked to lie on a table that will pass slowly through the scanner. 

The CT portion of the scan will be completed first, during which time you may be asked to hold your breath for several seconds; your technologist will communicate this to you if this is needed. During the scan it is important that you do not move. The length of the exam depends on your height and the clinical area that your physician is examining. On average PET/CT scans are completed within 45-60 minutes.
