Objective To investigate the application of 3D power doppler ultrasound (3D-PDU) and Shear wave elastography (SWE) on fetal growth restriction (FGR) placenta three-dimensional power doppler index and young's modulus value in quantitative analysis, and analyzes its diagnostic performance. Methods Thirty FGR pregnant women were selected as FGR group, and 45 healthy pregnant women were selected as control group. All pregnant women underwent three-dimensional power Doppler and shear wave elastography ultrasound examination from 25 to 36 weeks of gestation. Placental vascularization index (VI), flow index (FI), vascularization-flow index (VFI) and Young's modulus were collected. Results VI, FI, VFI in FGR group were significantly lower than those in control group (P<0.05). The Young's modulus of FGR group was higher than that of control group, and the difference was statistically significant (P<0.05). ROC curve shows the VI, FI and VFI in the area under the curve respectively 0.730, 0.673, 0.768. Conclusion Three-dimensional power doppler ultrasound parameters of joint shear wave elastography of FGR predictive value to a certain extent, and can be used for clinical screening of FGR.
