A PET/CT scan combines two powerful imaging techniques into a single exam. The PET (Positron Emission Tomography) portion shows how your body’s cells and tissues are functioning by detecting small amounts of a safe, radioactive tracer. The CT (Computed Tomography) portion provides precise anatomical detail, helping doctors pinpoint exactly where abnormal activity is occurring. When combined, PET/CT gives a more complete picture of health than either test alone.
The true value of PET/CT is in the answers it provides. For patients with cancer, it helps determine whether a tumor is present, if treatment is working, or if the disease has returned information that directly guides your care plan. In heart and brain conditions, it can reveal problems that might not be visible on other imaging, giving doctors the insight they need to make faster, more accurate decisions.
