本文回顾了MR指纹(MRF)的基本概念,其目标是突出MRF的主要贡献,将其与其他定量MRI文献相结合,并改进MRF的术语。本文讨论了稳健性和灵活性的MRF的签名字典匹配重建沿着更先进的MRF重建。MRF的一个关键特征是缺乏对信号演变的假设,这使科学家能够灵活地根据他们的需求定制序列。本文认为,独特的指纹的概念并没有捕获成功的参数映射的要求,分析信号的衍生物相对于生物物理参数,如弛豫时间,是更翔实的,因为它允许一个脉冲序列的效率进行评估。本文指出了磁流变液的效率,即翻转角的弛豫时间的时间尺度的变化的来源,并揭示了磁流变液的优势是最强的,在长扫描时间,所需的三维成像。此外,它概述了如何MRF的灵活性,可用于设计相互定制的脉冲序列和生物物理模型,以提高参数映射生物组织的再现性的目标。
This paper reviews the basic concept of MR fingerprinting (MRF) with the goal of highlighting MRF’s key contributions, putting them in the context of other quantitative MRI literature, and refining MRF’s terminology. The article discusses the robustness and flexibility of MRF’s signature dictionary-matching reconstruction along with more advanced MRF reconstructions. A key feature of MRF is the lack of assumptions about the signal evolution, which gives scientists the flexibility to tailor sequences for their needs. The paper argues that the concept of unique fingerprints does not capture the requirements for successful parameter mapping and that an analysis of the signal’s derivatives with respect to biophysical parameters, such as relaxation times, is more informative as it allows one to evaluate the efficiency of a pulse sequence. The paper points at the source of MRF’s efficiency, namely flip angle variations at the time scale of the relaxation times, and reveals that MRF’s advantages are strongest at long scan times, as required for 3D imaging. Further, it outlines how MRF’s flexibility can be used to design mutually tailored pulse sequences and biophysical models with the goal of improving the reproducibility of parameter mapping biological tissue.
