- A 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 form the body as a radionuclide decays.
- The technique is used commonly in human medicine:
- To assess organ function.
- For anatomical studies.
- Images may be dynamicor 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 lifes and this property may be utilized in different imaging techniques.
