An AI-driven fetal monitoring model to predict fetal growth restriction infants
Fetal growth restriction, small-for-gestational-age
In this research, the participants will undergo routine prenatal ultrasound scans throughout the entire pregnancy. This involves approximately five scans in total, which are conducted during the first, second and third trimesters. Besides that, the participants will have a non-invasive blood test during the first ultrasound scan, where 5 ml of blood will collect one time only. Every scan measures the fetus's growth to identify the growth-restricted fetuses earlier and take action to improve the outcomes for the growth-restricted fetus. The total duration of observation is typically from Week 11-14 until Week 36, which is around 6 months. The frequency of scans varies depending on the fetus’s condition, with some participants requiring weekly or bi-weekly scans.
