To obtain measurements of the normal fetal brain before 24 weeks of gestation (GW), a deadline for medical decisions on fetal viability in a large number of countries.
We retrospectively reviewed 70 normal MR examinations of fetuses aged GW 17 to 23. The fronto-occipital diameter, the cerebral bi-parietal diameter, the transverse cerebellar diameter, the vermian height, and antero-posterior diameter were measured.
The median, maximum, and minimum values for each parameter were displayed for each individual GW.
The recorded data might contribute to a better assessment of fetal health by providing normal boundaries for the brain growth.
为了在许多国家对胎儿生存能力做出医疗决策的 24 孕周截止日前获得胎儿 24 孕周前的正常脑部测量值。
我们回顾性分析了 70 例胎龄为 17 至 23 周的正常胎儿磁共振检查。测量了额枕径、大脑双径、横径小脑、蚓部高度和前后径。
显示了每个个体 GW 时每个参数的中位数、最大值和最小值。
记录的数据可能通过为大脑生长提供正常范围，有助于更好地评估胎儿健康。
