Prostate cancer recurrence is common after radical radiotherapy and the increasing use of novel, minimally invasive salvage treatments means that accurate detection and localization of radiorecurrent disease is vital in treatment planning and delivery. PET–CT is increasingly used to detect metastatic disease; however, data regarding its value for identifying and accurately characterizing intraprostatic recurrence need improvement.
