Nuclear imaging is the branch of imaging involving the administration of trace amounts of radiopharmaceuticals within the body to produce diagnostic images along with the aid of special gamma cameras and computers. These images are used to assess organ function, and are an effective tool for early diagnosis, as the function of the organ is assessed at the molecular level.
PET CT scan is a non-invasive nuclear imaging tool, which is used to assess blood flow to the organs and their function. As with many other nuclear imaging studies, a minute amount of radioactive tracer (Rubidium or 18F-FDG, depending upon the scan) is injected into the blood to assist a Gamma camera and computer with capturing images of the organ. At Owensboro Medical Practice, we offer both Cardiac PET and Oncology PET scans.
