Methods A total of 742 fetuses with normal fetal anatomy between 16 and 37+6 w.g. were included in this prospective study. The length and width of CSP was measured in the transthalamic plane and the CSP ratio was calculated. In all cases CSP was measurable. The mean and the standard (SD) of CSP ratio was presented in 2-week intervals and regression analysis was used to assess the relationship between CSP ratio and gestational age. Conclusion The study is the first to present nomograms of the fetal CSP ratio in the Bulgarian population which can be used in assessment of both normal and abnormal fetal brain development.
