Biopsy has become a cornerstone of modern medicine and most modern biopsies are performed percutaneously using image guidance, typically computed tomography or ultrasound. MR-guided biopsy offers many advantages over these more traditional modalities, and the recent development of interventional MR imaging techniques has made MR-guided percutaneous biopsies and aspirations a clinical reality. As the field of MR-guided procedures continues to expand and to attract more attention from radiologists, it is important to understand the concepts, techniques, applications, advantages, and limitations of MR-guided biopsy/percutaneous procedures. Radiologists should also recognize the need for their significant involvement in the technical aspects of MR-guided procedures, since several user-defined parameters can alter device visualization in the MR imaging environment and affect procedure safety. This article reviews the prerequisites, systems, and applications of MR-guided biopsy.
活检已成为现代医学的基石，大多数现代活检是在图像引导下经皮进行的，通常使用计算机断层扫描或超声。与这些更传统的方式相比，磁共振引导活检具有许多优势，并且介入性磁共振成像技术的最新发展已使磁共振引导下的经皮活检和穿刺抽吸成为临床现实。随着磁共振引导程序领域的不断扩展并吸引放射科医生更多的关注，了解磁共振引导活检/经皮程序的概念、技术、应用、优势和局限性非常重要。放射科医生还应认识到他们需要大量参与磁共振引导程序的技术方面，因为几个用户定义的参数会改变磁共振成像环境中的设备可视化并影响程序安全性。本文综述了磁共振引导活检的先决条件、系统和应用。
