Increased uptake of 99m Tc-diphosphonate by ischemic or dying cells is linked to the abnormal intracellular influx of ionic calcium, usually caused by decreased blood flow (Wahner and Dewanjee 1981 ). phalangeal areas. To better see some bones in your body, your doctor might order additional imaging called single-photon emission computerized tomography (SPECT). It's also called a "bone scintigraphy" or "technetium-99m-MDP scan." During a bone scan, you get a small amount of radioactive material called a "radionucleotide" (or tracer).

An FDG PET scan is one of the most powerful tools we have to detect and monitor disease. A Rogel Cancer Center oncologist explains the diagnosis and how its treated. Dr. Stone is a physician for Smuin Ballet and has served as a physician for the U.S. 1 What does focal uptake mean on a bone scan? Idiopathic destructive arthropathy (Milwau- kee shoulder).2'21 6. These areas appear as darker "hot spots" and lighter "cold spots" where the tracers have or haven't accumulated. Imaging techniques for evaluation of the painful joint. Most commonly they are located in the vertebrae (of the thoracic spine 5 ), followed by the skull and facial bones, followed by long bones where they preferentially involve the . Some bones can normally appear slightly darker than other bones because of their increased metabolic activity. Hot spots may be caused by a fracture that is healing, bone cancer, a bone infection (osteomyelitis), arthritis, or a disease of abnormal bone metabolism (such as Paget's disease). These Intense uptake generally means lots of bone metabolism. Others can cause decreased uptake of radioactive material.
