超快序列的发展导致了胎儿MRI的显著改善。成像协议必须调整到快速发展的胎儿中枢神经系统（CNS）和临床问题。序列参数必须改变，以科普相应的发展阶段，以产生图像的运动伪影，并提供最佳的可视化区域和重点的兴趣。与产后检查相反，每一个可疑的胎儿中枢神经系统异常都需要检查整个胎儿和胎儿外的宫内结构，包括子宫。这种方法涵盖了胎儿中枢神经系统疾病的两个方面：孤立的和复杂的畸形和胎儿胎盘单位的完整性受损引起的脑病变。
The development of ultrafast sequences has led to a significant improvement in fetal MRI. Imaging protocols have to be adjusted to the rapidly developing fetal central nervous system (CNS) and to the clinical question. Sequence parameters must be changed to cope with the respective developmental stage, to produce images free from motion artefacts and to provide optimum visualization of the region and focus of interest. In contrast to postnatal studies, every suspect fetal CNS abnormality requires examination of the whole fetus and the extrafetal intrauterine structures including the uterus. This approach covers both aspects of fetal CNS disorders: isolated and complex malformations and cerebral lesions arising from the impaired integrity of the fetoplacental unit.
