Abstract

Several advantages of MR imaging compared with other imaging modalities have provided the rationale for increased attention to MR-guided interventions, including its excellent soft tissue contrast, its capability to show both anatomic and functional information, and no use of ionizing radiation. An important aspect of MR-guided intervention is to provide visualization and navigation of interventional devices relative to the surrounding tissues. This article focuses on the methods for MR-guided active tracking in catheter-based interventions. Practical issues about implementation of active catheter tracking in a clinical setting are discussed and several current application examples are highlighted.

摘要

与其他成像方式相比,磁共振成像(MR)具有诸多优势,这为人们更多地关注MR引导下的介入治疗提供了理论依据,这些优势包括其出色的软组织对比度、显示解剖和功能信息的能力以及不使用电离辐射。MR引导介入的一个重要方面是提供介入设备相对于周围组织的可视化和导航。本文重点介绍基于导管介入中MR引导主动跟踪的方法。讨论了在临床环境中实施主动导管跟踪的实际问题,并突出了几个当前的应用实例。
