Ultrasound Assessment of Fetal Growth Parameters

The goal of this observational study is to establish reference value ranges for normal fetal biometric parameters at different gestational weeks for the domestic population, and evaluate their clinical application to predict perinatal outcomes. The main question it aims to answer is: What is the relationship between fetal parameter measurements (such as clavicle length, scapular width, scapular length, sternum length, and cranial structure measurements) and gestational age as well as other growth parameters? And how can these parameters be used in clinical applications such as predicting perinatal outcomes? Researchers will observe the relationship between the measurement values of fetal clavicle length, scapular width, scapular length, sternum length, and cranial structure and gestational age as well as other growth parameters, and ultimately follow up on the perinatal outcomes of mother and fetus.
