This article describes the use of placental magnetic resonance imaging (MRI) relaxation times in the in vivo assessment of placental function. It focuses on T2*-weighted placental MRI, the main area of the authors' research over the past decade. The rationale behind T2*-weighted placental MRI, the main findings reported in the literature, and directions for future research and clinical applications of this method are discussed. The article concludes that placental T2* relaxation time is an easily obtained and robust measurement, which can discriminate between normal and dysfunctional placenta. Placenta T2* is a promising tool for in vivo assessment of placental function.
本文描述了胎盘磁共振成像（MRI）弛豫时间在胎盘功能的体内评估中的应用。它侧重于 T2*-加权胎盘 MRI，这是作者过去十年研究的主要领域。讨论了 T2*-加权胎盘 MRI 的基本原理、文献中报告的主要发现以及该方法的未来研究和临床应用方向。文章得出结论，胎盘 T2弛豫时间是一种易于获得且稳健的测量方法，可区分正常和功能失调的胎盘。胎盘 T2是一种有前途的胎盘功能体内评估工具。
