Document Summary
Distinguish between the various particles involved in gamma decay and positron decay. Explain how radiation emitted from the body is externally detected using pet and. Explain factors that limit the noise-resolution performance of spect and pet systems. Describe strategies for reconstructing spect and pet images. Describe the effects of attenuation, scatter, randoms, collimator response, and detector response for spect and pet. Assess the safe working conditions in regards to radiation protection and radiation safety principles for spect/pet procedures. Images show the distribution of function within an organ. Maps of biodistribution of admin radiolabelled compound. Radionuclide suited to image depending on its half-life. Amount of uptake of radionuclide represents the amount of function directly. Stages in a nuclear medicine procedure: production of the radionuclide, production of the radiopharmaceutical, administration to the patient, imaging and/or sample counting. Can be used for diagnosis and/or therapy. Can detect diseases earlier than anatomic imaging modalities.
