Fetal growth assessment (Đánh giá sự tăng trưởng của thai nhi) là quá trình y khoa sử dụng các kỹ thuật chẩn đoán hình ảnh (phổ biến nhất là siêu âm) để đo lường và theo dõi sự phát triển của em bé trong bụng mẹ, từ đó đảm bảo thai kỳ khỏe mạnh và can thiệp kịp thời nếu có bất thường.

The measurements of fetal HC, AC and FL are plotted on the reference range with gestational age reported by: Snijders RJ, Nicolaides KH. Fetal biometry at 14–40 weeks’ gestation. Ultrasound Obstet Gynecol 1994;4:34-48.
The estimated fetal weight from the measurements of HC, AC and FL is derived from the formula reported by: Hadlock FP, Harrist RB, Martinez-Poyer J. In utero analysis of fetal growth: a sonographic weight standard. Radiology 1991;181:129-133.
The estimated fetal weight is plotted on the reference range for gestational age derived from the formula reported by: Nicolaides KH, Wright D, Syngelaki A, Wright A, Akolekar R.
