氘代谢光谱 (DMS) 和成像 (DMI) 最近被描述为简单而强大的基于 MR 的方法,以高时间和/或空间分辨率绘制代谢图。多种合适的氘化底物(包括葡萄糖和乙酸盐)的代谢命运可以通过氘 MR 方法进行监测,其中氘的有利 MR 特性可防止许多妨碍其他技术的并发症。较短的 T1 弛豫时间可带来良好的 MR 灵敏度,而较低的自然丰度则无需抑制水或脂质。氘光谱的稀疏性与低共振频率相结合提供了对磁场不均匀性的相对免疫力。总而言之,这些功能结合成一种高度稳健的代谢成像方法,该方法具有成为占主导地位的 MR 研究工具和可行的临床成像模式的强大潜力。本视角回顾了氘作为代谢示踪剂的历史、NMR 作为氘体外和体内检测方法的使用以及 DMS 和 DMI 的最新发展。在回顾了氘的 NMR 特性和生物效应后,概述了 DMI 的光明前景。
Deuterium metabolic spectroscopy (DMS) and imaging (DMI) have recently been described as simple and robust MR-based methods to map metabolism with high temporal and/or spatial resolution. The metabolic fate of a wide range of suitable deuterated substrates, including glucose and acetate, can be monitored with deuterium MR methods in which the favorable MR characteristics of deuterium prevent many of the complications that hamper other techniques. The short T1 relaxation times lead to good MR sensitivity, while the low natural abundance prevents the need for water or lipid suppression. The sparsity of the deuterium spectra in combination with the low resonance frequency provides relative immunity to magnetic field inhomogeneity. Taken together, these features combine into a highly robust metabolic imaging method that has strong potential to become a dominant MR research tool and a viable clinical imaging modality. This perspective reviews the history of deuterium as a metabolic tracer, the use of NMR as a detection method for deuterium in vitro and in vivo and the recent development of DMS and DMI. Following a review of the NMR characteristics and the biological effects of deuterium, the promising future of DMI is outlined.
