With a 40‐year history of use for in vivo studies, the terminology used to describe the methodology and results of magnetic resonance spectroscopy (MRS) has grown substantially and is not consistent in many aspects. Given the platform offered by this special issue on advanced MRS methodology, the authors decided to describe many of the implicated terms, to pinpoint differences in their meanings and to suggest specific uses or definitions. This work covers terms used to describe all aspects of MRS, starting from the description of the MR signal and its theoretical basis to acquisition methods, processing and to quantification procedures, as well as terms involved in describing results, for example, those used with regard to aspects of quality, reproducibility or indications of error. The descriptions of the meanings of such terms emerge from the descriptions of the basic concepts involved in MRS methods and examinations. This paper also includes specific suggestions for future use of terms where multiple conventions have emerged or coexisted in the past.

体内 MR 光谱方法和 MR 光谱表征的术语和概念：背景和专家的共识建议

具有 40 年的体内研究使用历史，用于描述磁共振波谱 (MRS) 方法和结果的术语已经大幅增长，并且在许多方面并不一致。鉴于本期关于高级 MRS 方法论的特刊提供的平台，作者决定描述许多相关术语，以查明其含义的差异并提出具体用途或定义。这项工作涵盖了用于描述 MRS 各个方面的术语，从 MR 信号的描述及其理论基础到采集方法、处理和量化程序，以及涉及描述结果的术语，例如，用于质量、再现性或错误迹象等方面。这些术语的含义描述来自于 MRS 方法和检查中涉及的基本概念的描述。本文还包括对过去出现或共存多种约定的术语的未来使用的具体建议。
