A PET Scan or Positron Emission Tomography is a diagnostic imaging test used in medicine. It uses a radioactive substance known as a tracer to look for disease or abnormalities in the body. PET scans provide detailed 3-dimensional images, mostly used for detecting cancer, heart abnormalities and brain disorders. This scan is highly effective in revealing or evaluating several conditions as it shows how organs and tissues are functioning.
Read full definition→A PET/CT scan is a combination of two imaging techniques. PET (Positron Emission Tomography) reveals the body's metabolic activity, while CT (Computed Tomography) provides detailed anatomic information. By merging these two techniques into a single scan, doctors can more accurately diagnose, monitor, and treat diseases, particularly cancer, by pinpointing their exact location and extent in the body.
