目前，人体磁共振(MR)检查正变得高度专业化，具有预先定义的、通常是相对较小的体内靶点。传统上，临床磁共振设备被设计成通用的，这损害了它对小目标的效率。在这里，我们提出了靶向临床磁共振成像(MRI)的概念，它可以直接集成到现有的临床MR系统中，并论证了其用于乳房成像的可行性。这一概念包括在人工谐振器的帮助下对射频磁通量进行空间重新分布和被动聚焦，以最大限度地提高感兴趣区域的传统MR系统的效率。这种方法提供了有针对性的MRI的前景，并为现有MR系统中的高质量专门MR检查带来了新的机会。在这里，作者提出了一个概念，有针对性的临床磁共振成像的相对较小的目标在体内。他们使用人工谐振器对射频磁通量进行空间重新分配和被动聚焦，并证明了靶向乳房成像的可行性。
Currently, human magnetic resonance (MR) examinations are becoming highly specialized with a pre-defined and often relatively small target in the body. Conventionally, clinical MR equipment is designed to be universal that compromises its efficiency for small targets. Here, we present a concept for targeted clinical magnetic resonance imaging (MRI), which can be directly integrated into the existing clinical MR systems, and demonstrate its feasibility for breast imaging. The concept comprises spatial redistribution and passive focusing of the radiofrequency magnetic flux with the aid of an artificial resonator to maximize the efficiency of a conventional MR system for the area of interest. The approach offers the prospect of a targeted MRI and brings novel opportunities for high quality specialized MR examinations within any existing MR system. Here, the authors present a concept for targeted clinical magnetic resonance imaging for relatively small targets in the body. They use an artificial resonator for spatial redistribution and passive focusing of the radiofrequency magnetic flux and demonstrate feasibility for targeted breast imaging.
