Abstract:
Objective To observe the value of three-dimensional ultrasound virtual organ computer-aided analysis(VOCAL)technique for measuring choroid plexus volume(CPV)and lateral ventricle volume(LVV)in normal fetus of 11-13+6 gestational weeks.Methods Three-dimensional ultrasonic data of 428 normal singletons at 11-13+6 gestational weeks were retrospectively analyzed.The fetuses were divided into 11-11+6 weeks group(n=77),12-12+6 weeks group(n=225)and 13-13+6 weeks group(n=126).Fetal CPV,LVV and CPV/LVV ratio were measured and calculated using VOCAL technique and compared between groups.Pearson correlation analysis was performed to observe the correlations of CPV,LVV,CPV/LVV ratio with crown-rump length(CRL).Results Significant differences of CPV,LVV and CPV/LVV ratio were found among groups(all P＜0.05).Among 11-11+6 weeks group,12-12+6 weeks group and 13-13+6 weeks group,CPV and LVV increased progressively,while CPV/LVV ratio decreased progressively(all adjusted P＜0.05).During 11-13+6 gestational weeks,CPV and LVV were both highly positively correlated with CRL(r=0.904,0.929,both P＜0.05),while CPV/LVV ratio was highly negatively correlated with CRL(r=-0.893,P＜0.05).Conclusion Three-dimensional ultrasound VOCAL technique was feasible for measuring CPV and LVV in normal fetus of 11-13+6 gestational weeks.
