Prenatal ultrasound evaluation of the fetal brain requires documentation of specific structures according to guidelines set by the American College of Radiology and the American Institute of Ultrasound in Medicine. Among these required structures are: cerebellum, cisterna magna, lateral cerebral ventricles, choroid plexus, midline falx, and cavum septum pellucidum. All these structures can be visualized in three crucial planes of imaging that include cisterna magna/cerebellum, cavum septum pellucidum, and ventricular atria. A systematic approach can be achieved by instituting a protocol that includes these three basic levels of imaging of the fetal head. These anatomical levels should be incorporated in daily routine for complete obstetric ultrasound evaluation.
胎儿脑部的产前超声评估需要根据美国放射学会和美国医学超声学会制定的指南记录特定结构。这些必需的结构包括：小脑、枕大池、侧脑室、脉络丛、中线大脑镰和透明隔腔。所有这些结构都可以在三个关键成像平面中显示，包括枕大池/小脑、透明隔腔和心室心房。通过制定包含胎儿头部这三个基本成像水平的方案，可以实现系统的方法。这些解剖学水平应纳入产科超声完整评估的日常流程中。
