A Neck PET/CT Scan at Radiology Associates; What to Expect.
What is a PET/CT scan?
PET, or Positron Emission Tomography, is used primarily to detect the presence and severity of cancers. PET works by using a glucose radiotracer that is detected by a small camera to measure the way sugar is being used by the body. Because cancer cells function and grow faster, they use more sugar than normal cells. PET can be used to diagnose, stage, and restage cancer. It can also monitor the bodyâ€™s response to a wide array of therapies such as chemotherapy or radiation.
Computed Tomography, known as CT or CAT scan, uses computers and x-rays to produce images of the inside of the body. CT imaging is used to show more detail of soft tissue, like the brain, as well as dense tissue, like bone. Multiple CT images are stacked like slices of a loaf of bread.
By combining PET and CT technology and fusing the images, Radiology Associates is able to create the highest quality images to detect abnormalities or cancer â€¦ better and earlier.
