This literature review provides data on the temporal sequence in which gyri, sulci, and fissures first become apparent on anatomic specimens of the developing brain surface. Ultrasonic display of these anatomic features lags behind the initial appearance of the features by a variable interval, greater in early gestation and diminishing in late gestation. MR imaging, especially three-dimensional surface rendering, displays the degree of surface maturation to advantage. Different publications have provided variable estimates of the time course of surface maturation, leading to discordance in the date tabulated. None-the-less, the overall sequence is clear and the surface features are useful in assessing the degree of fetal-neonatal maturity by ultrasonography and by MR imaging.
这篇文献综述提供了关于脑回、脑沟和脑裂在发育中脑表面解剖标本上首次显现的时间顺序的数据。这些解剖特征的超声显示比其最初出现的时间滞后一段可变的间隔，在妊娠早期间隔较长，在妊娠晚期逐渐缩短。磁共振成像，尤其是三维表面重建，能很好地显示表面成熟程度。不同的出版物对表面成熟的时间进程给出了不同的估计，导致列表中的日期不一致。尽管如此，总体顺序是清晰的，并且这些表面特征有助于通过超声和磁共振成像评估胎儿-新生儿的成熟程度。
