Prostate brachytherapy offers and effective treatment for organ-confined prostate carcinoma. It is rapidly delivered compared with external beam radiation therapy or surgery and well tolerated by patients. Volumetric imaging and image guidance play critical roles in patient selection, treatment planning, treatment delivery, and postimplant assessment. Costs, availability and ease of use often dictate the local and regional differences in imaging approach, whether ultrasound, CT, or MR. Future volumetric image developments may permit multimodality image fusion to integrate tumor-specific imaging such as MR spectroscopy or positron emission tomography/CT into real-time ultrasound, CT, or MR.
前列腺近距离放射治疗为局限性前列腺癌提供了一种有效的治疗方法。与外照射放疗或手术相比，它的治疗过程迅速，且患者耐受性良好。容积成像和图像引导在患者选择、治疗计划、治疗实施以及植入后评估中发挥着关键作用。成本、可获得性和易用性常常决定了成像方法在当地和地区的差异，无论是超声、CT还是MR。未来的容积图像发展可能允许多模态图像融合，将诸如磁共振波谱或正电子发射断层扫描/CT等肿瘤特异性成像整合到实时超声、CT或MR中。
