The purpose of this study is to create reference values for fetal ultrasound parameters using an internationally agreed-upon creation method. Specifically, we will collect ultrasound parameters from multiple institutions in a forward-looking manner, analyze them using a regression model with ultrasound parameters as the response variable (Y) and the number of weeks of gestation as the predictor variable (X), and report the reference values for each parameter.
