Recent technological advances in fetal magnetic resonance imaging (MRI) and increased reliability of MRI in depicting abnormalities and lesions, especially in the central nervous system, are increasingly bringing up challenging issues with regard to accurate diagnosis. There are also pitfalls not only attributable to image acquisition but also in clinical interpretation. The misinterpretation of findings because of insufficient knowledge about fetal brain development as visualized by MRI may also be regarded as an important limitation of fetal MRI. We provide an overview of the most common pitfalls experienced in fetal MRI in routine practice, demonstrate how to identify some of the factors that lead to imaging misinterpretation, and suggest ways to tackle these problems, with an emphasis on MR techniques and image calibration.
胎儿磁共振成像（MRI）的最新技术进展以及MRI在描绘异常和病变（尤其是中枢神经系统方面）的可靠性不断提高，在准确诊断方面日益带来具有挑战性的问题。不仅在图像采集方面存在陷阱，在临床解读中也存在。由于对MRI显示的胎儿大脑发育知识不足而导致对检查结果的错误解读，也可被视为胎儿MRI的一个重要局限性。我们概述了常规实践中胎儿MRI最常见的陷阱，展示了如何识别一些导致成像错误解读的因素，并提出解决这些问题的方法，重点是MR技术和图像校准。
