在体内应用中，核磁共振光谱数据的质量很容易受到影响。有几个因素可能会产生信号伪影，而且这些伪影通常不容易被检测到，即使是经验丰富的光谱学家也很难检测到。可靠和可重复的体内mr数据需要定义质量要求和目标，实施保证质量标准的措施，定期控制数据质量，并不断寻求质量改进。本综述的第一部分包括对MR质量管理的不同方面的一般介绍，随后描述了一系列可用于确保MR系统质量的测试和模型。第三部分介绍了光谱数据质量控制的几种方法和策略。本文总结了一些有意义的技术和方面，可能有助于进一步提高体内磁共振光谱的质量。(C) 2017爱思唯尔公司版权所有。
The quality of MR-Spectroscopy data can easily be affected in in vivo applications. Several factors may produce signal artefacts, and often these are not easily detected, not even by experienced spectroscopists. Reliable and reproducible in vivo MRS-data requires the definition of quality requirements and goals, implementation of measures to guarantee quality standards, regular control of data quality, and a continuous search for quality improvement.The first part of this review includes a general introduction to different aspects of quality management in MRS. It is followed by the description of a series of tests and phantoms that can be used to assure the quality of the MR system. In the third part, several methods and strategies used for quality control of the spectroscopy data are presented. This review concludes with a reference to a few interesting techniques and aspects that may help to further improve the quality of in vivo MR-spectra. (C) 2017 Elsevier Inc. All rights reserved.
