What is a PET/CT scan?

Northern California PET Imaging Center Educational Video - 2015 PET (Positron Emission Tomography) imaging pinpoints metabolic activity in cells of the human body. Metabolic changes in disease often occur before structural changes that can be seen on CT. PET/CT fuses these two images together allowing the physician to view the metabolic changes in the proper anatomical context of the body. PET/CT imaging is most commonly used to assist with the diagnosis and monitoring of cancer, cardiac disease, Alzheimer’s disease and other dementias. www.NorCalScans.org
