Proton magnetic spectroscopy (1H-MRS) is a noninvasive imaging technique that allows for the quantification of neurometabolic compounds at millimolar concentrations in the living human brain. This technique has been most often used to assess long-term changes in human brain metabolism in psychiatric disorders, pharmacological treatment, chronic drug use, and alcohol dependence. In contrast, the capacity of 1H-MRS to evaluate the biochemical changes in the minutes to hours following drug consumption, which contribute to fast-acting drug-induced changes in perception, mood, cognition, and behavior, is largely unexplored. This Viewpoint highlights the utility of 1H-MRS imaging for revealing neural mechanisms of rapid drug action in the human brain, with implications for phasic, in vivo changes in biosynthetic and catabolic pathways after drug exposure. Drawing from examples of psychostimulant drug effects, neuromodulatory input and drug-induced mood, we present strategies to optimize 1H-MRS for noninvasively imaging fast-acting drug effects and other rapid phenomena within the living human brain. These approaches could provide powerful tools for both basic research and drug development.

使用1H-MRS对人的速效药物作用进行成像。

质子磁光谱法(1 H-MRS)是一种非侵入性成像技术,可对人体内活体大脑中毫摩尔浓度的神经代谢化合物进行定量。该技术最常用于评估精神疾病,药物治疗,慢性药物使用和酒精依赖中人脑代谢的长期变化。相比之下,1 H-MRS评估吸毒后数分钟至数小时内生化变化的能力尚未得到充分研究,该能力可导致速效药物诱导的感知,情绪,认知和行为变化。该观点突出了1的效用H-MRS成像揭示了人脑中快速药物作用的神经机制,并揭示了药物暴露后生物合成和分解代谢途径的阶段性,体内变化。从精神刺激药物作用,神经调节性输入和药物诱导的情绪的例子中汲取经验,我们提出了优化1 H-MRS的策略,用于非侵入性地成像活人大脑内的速效药物作用和其他快速现象。这些方法可以为基础研究和药物开发提供强大的工具。
