Image-based radiation treatment planning and localization have contributed to better targeting of the prostate and sparing of normal tissues. Guidelines are needed to address radiation dose delivery, including patient setup and immobilization, target volume definition, treatment planning, treatment delivery methods, and target localization. Guidelines for external-beam radiation treatment planning have been updated and are presented here. The use of appropriate doses, simulation techniques, and verification of field setup are essential for the accurate delivery of radiation therapy. The ACR Appropriateness Criteria(®) are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment.
