摘　　要：目的 观察三维超声虚拟器官计算机辅助分析软件(VOCAL)技术测量妊娠11~13^(+6)周正常胎儿脉络丛体积(CPV)及侧脑室体积(LVV)的价值。方法 回顾性分析妊娠11~13^(+6)周428胎正常单胎胎儿三维超声资料,将其分为11~11^(+6)周组(n=77)、12~12^(+6)周组(n=225)及13~13^(+6)周组(n=126);利用VOCAL技术测算胎儿CPV、LVV及CPV/LVV比值并进行组间比较,以Pearson相关分析观察CPV、LVV及CPV/LVV比值与头臀长(CRL)的相关性。结果 3组CPV、LVV及CPV/LVV比值差异均有统计学意义(P均<0.05);11~11^(+6)周组、12~12^(+6)周组及13~13^(+6)周组胎儿CPV及LVV依次增加,而CPV/LVV比值依次减小(校正P均<0.05)。妊娠11~13^(+6)周,CPV及LVV与CRL均呈高度正相关(r=0.904、0.929,P均<0.05),而CPV/LVV比值与CRL呈高度负相关(r=-0.893,P<0.05)。结论 三维超声VOCAL技术可用于测量妊娠11~13^(+6)周正常胎儿CPV及LVV。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.
