Prostate brachytherapy is a radiotherapy technique for early stage prostate cancer that uses imaging guidance to place radioactive sources directly into the prostate gland. Transrectal ultrasound is used to facilitate a template-guided transperineal approach to the prostate and permits a highly conformal method of prostate radiotherapy with doses far higher than can be achieved with other radiation techniques. Maturing data has validated this technique as an acceptable treatment option with favourable and durable biochemical outcomes. The radiologist has a major role to play in the process: patient selection, guiding source delivery and follow-up after treatment all require close collaboration with colleagues in Radiation Oncology and Medical Physics. This review emphasises the specific contribution of imaging in the context of currently reported outcomes data.
前列腺近距离放射治疗是一种针对早期前列腺癌的放射治疗技术，它利用影像引导将放射源直接植入前列腺腺体。经直肠超声用于辅助经会阴模板引导下的前列腺穿刺，从而实现一种高度适形的前列腺放射治疗方法，其剂量远高于其他放射技术所能达到的剂量。不断完善的数据已证实该技术是一种可接受的治疗选择，能带来良好且持久的生化治疗效果。放射科医生在这一过程中发挥着重要作用：患者选择、引导放射源植入以及治疗后的随访都需要与放射肿瘤学和医学物理领域的同事密切合作。本综述强调了在当前报告的疗效数据背景下影像检查的具体作用。
