Dose Reduction in Hybrid Imaging Techniques in Nuclear Medicine

Educational Objectives:

  1. Discover the principles of radiation protection
  2. Understand the modalities of optimisation of radiation exposure for the patients undergoing nuclear medicine procedures in diagnostic and therapy
  3. Learn about the ways to reduce the exposure doses for the patients and understand the limits of the principle of dose reduction
  4. Achieve the background knowledge able to reduce the exposure of the patients in conventional but also in hybrid nuclear medicine imaging techniques
  5. Find useful methods to optimise in the daily practice the exposure of the patients diagnosed or treated in nuclear medicine facilities


In the last two decades, the number of nuclear medicine procedures increased tremendously and consequently, it has been noted by all international regulatory bodies that the radiation dose produced by medical procedures has a greater contribution to the effective dose of individuals. It is necessary, therefore, to find and use all the modalities that may help to reduce the radiation exposure produced to the patients undergoing nuclear medicine procedures. In daily practice, the professionals working in nuclear medicine departments can follow several options to reduce the exposure caused to the patients: to decrease the administrated activity using different methods of calculation (based on body weight, height, body surface), to optimise the excretion of radiopharmaceutical (giving appropriate advices and recommendations to the patients related to this aspect), to use the appropriate radioisotope/radiopharmaceutical, to use high sensitive and high resolution imaging devices with optimal acquisition and reconstruction protocols, to use low-dose imaging protocols in hybrid techniques. The entire range of alternatives used to decrease the exposure dose of the patients must respect the optimisation principle of radiation protection expressed in international and/or national radiation protection directives and may not affect the quality of diagnostic information or the estimated therapeutic effect.
