- Virtual Reality for Dose Optimization in Pediatric Nuclear Medicine: Better Than the Real Thing (December 2011)
Zanzonico offers perspective on elements involved in balancing the benefits of advanced imaging techniques against risks of radiation exposure in young patients and previews a related article in this issue of JNM.
- Minimizing and Communicating Radiation Risk in Pediatric Nuclear Medicine (August 2011)
Fahey and colleagues provide an overview of radiation dosimetry for radiopharmaceuticals and CT, radiation risk estimation in pediatric nuclear medicine, approaches for communication of risk to patientsâ€™ families, and radiation dose reduction strategies.
- Cardiovascular Nuclear Imaging: Balancing Proven Clinical Value and Potential Radiation Risk - The Cardiovascular Council Board of Directors (July 2011)
Members of the SNM Cardiovascular Council Board of Directors summarize appropriate-use criteria and guidelines for minimizing radiation exposure and optimizing the clinical use of radionuclide cardiac imaging studies.
- Evaluation of Optimal Acquisition Duration or Injected Activity for Pediatric 18F-FDG PET/CT (July 2011)
Alessio and colleagues determine whether shorter acquisition durations or lower 18F-FDG injected activity could be used for pediatric 18F-FDG PET/CT examinations while maintaining diagnostic utility.
