Fetal growth restriction is the second leading cause of perinatal death, but its treatment is limited, so the prediction and risk assessment of fetal growth restriction has always been a hot spot in clinical and research work.In recent years, some high-quality researches in maternal risk factors of fetal growth restriction，ultrasonic doppler flow, magnetic resonance imaging, serological biomarkers and multi-parameter prediction assessment have made certain progress. We summarize and analyze these reaserches based on the China expert consensus of FGR（2019 Edition），hoping to provide some references for the prediction and early warning  of FGR.
