Abstract：Objective: To analyze placenta MRI features of fetal growth restriction (FGR) with different subtypes, and to provide evidence for FGR treatment. Methods: The clinical data of 36 pregnant women diagnosed with FGR were collected as the FGR group. 30 normal pregnant women were selected as the control group. All patients underwent MRI diffusion-weighted imaging (DWI) examination. And they were divided into symmetrical group and asymmetrical group according to the head circumference/length. The placenta MRI features of FGR with different subtypes were compared. Results: The placental thickness and placental volume of symmetrical FGR group were lower than those of asymmetrical FGR group and the control group. The placental apparent diffusion coefficient (ADC) value was lower than that of the control group (P<0.05). The placental volume of asymmetrical FGR group was lower than that of the control group, and placental ADC value was lower than that of symmetrical FGR group and the control group (P<0.05). The head circumference, length and the Apgar scores at 1 min after birth of symmetrical FGR group were lower than those of asymmetrical FGR group and the control group (P<0.05), and the weight was lower than that of the control group (P<0.05). The length, weight and and the Apgar scores at 1 min after birth in asymmetrical FGR group were lower than those in the control group (P<0.05). Except the weight, the other indexes were higher than those in symmetrical FGR group (P<0.05). The incidence of perinatal complications in symmetrical FGR group was slightly higher than that in asymmetrical FGR group and the control group (P>0.05). Conclusion: The MRI of symmetrical FGR is characterized by low placental thickness, volume and ADC value. The placenta thickness is basically normal in asymmetrical FGR, and the decrease of placental volume is short of symmetrical type. But the decrease of ADC value is significant.
