Which patients benefit from post-implant CT dosimetry after real-time intraoperative planning for low dose rate prostate brachytherapy? Case series and systematic literature review

摘要

IntroductionAt present, post-implant CT-based dosimetry is a standard quality assurance practice following low dose rate (LDR) prostate brachytherapy. However, it rarely influences management and involves radiation exposure, costs and inconvenience. The purpose of our study was to assess the need for post-implant CT-based dosimetry through correlation with pre-implant and real-time dosimetry and review its place in the management of patients treated with LDR brachytherapy, so that it could be undertaken more selectively.
