Introduction

  • radiopharmaceutical is a chemical containing a radionuclide (radioactive atom) that is used for diagnostic or therapeutic medicine.
  • Scintigraphy is the process of detection and measurement of the gamma radiation released from the body as a radionuclide decays.
  • The technique is used commonly in human medicine:
    • To assess organ function.
    • For anatomical studies.
  • Images may be dynamic or static giving information about function or structure respectively.
  • Different radiopharmaceuticals are suitable for imaging different body systems and for different purposes.
    • Radionuclides can be bound to chemicals that are preferentially taken up in specific organs.
    • Radionuclides have different half-lives, and this property may be utilized in different imaging techniques.
