磁共振成像是目前最有效的诊断成像工具，可视化的解剖和病理的前列腺。目前，经直肠超声的实用性和成本效益占主导地位的图像引导针为基础的前列腺干预。整合诊断和介入MR成像的挑战包括缺乏实时反馈、成像技术的复杂性以及在MR成像扫描仪的几何约束内对会阴的有限访问。在文献中探索并临床证明了两种基本策略：（1）将先前采集的诊断性MR成像与介入性TRUS或开放式扫描仪MR图像配准，以及（2）使用仔细的患者定位或简单操纵器辅助，在传统诊断扫描仪内进行立体定向针介入。目前，研究人员正在开发的技术，使磁共振成像的方法的选择，直接指导许多程序。本文重点介绍了前列腺癌的穿刺介入治疗，包括活检、近距离放射治疗和热疗。随着前列腺生物成像技术的快速发展，作者认为MR成像引导在前列腺癌的诊断和治疗中将发挥越来越大的作用。
MR imaging is currently the most effective diagnostic imaging tool for visualizing the anatomy and pathology of the prostate gland. Currently, the practicality and cost effectiveness of transrectal ultrasound dominates image guidance for needle-based prostate interventions. Challenges to the integration of diagnostic and interventional MR imaging have included the lack of real-time feed-back, the complexity of the imaging technique, and limited access to the perineum within the geometric constraints of the MR imaging scanner. Two basic strategies have been explored and clinically demonstrated in the literature: (1) coregistration of previously acquired diagnostic MR imaging to interventional TRUS or open scanner MR images, and (2) stereotactic needle interventions within conventional diagnostic scanners using careful patient positioning or the aid of simple manipulators. Currently, researchers are developing techniques that render MR imaging the method of choice for the direct guidance of many procedures. This article focuses on needle-based interventions for prostate cancer, including biopsy, brachytherapy, and thermal therapy With rapid progress in biologic imaging of the prostate gland, the authors believe that MR imaging guidance will play an increasing role in the diagnosis and treatment of prostate cancer.
