| 目的 探讨采用三维超声容积自动测量（VOCAL）技术不同旋转步进角度测量中晚孕期胎儿胆囊体积的一致性，并分析其与孕周的相关性。方法 对157名接受产前筛查的孕妇，采用三维超声VOCAL技术，分别选择旋转步进角度30°、18°、12°，测量胎儿胆囊体积，观察胎儿胆囊体积与孕周的相关性，并比较3种旋转步进角度测量胎儿胆囊体积的一致性。结果 30°、18°、12°旋转步进角度测得胎儿胆囊体积值均与孕周相关性高（r=0.92、0.88、0.90，P均<0.001），且30°与18°（ICC=0.94）、30°与12°（ICC=0.97）及18°与12°（ICC=0.94）测量胎儿胆囊体积的一致性均良好。结论 采用三维超声VOCAL技术不同旋转步进角度测量胎儿胆囊体积值的一致性良好，且均与孕周高度相关。 |

| Objective To investigate the consistency of fetal gallbladder volume (FGV) during middle-late pregnancy with three-dimensional ultrasonic virtual organ computer-aided analysis (VOCAL) technique at different rotation angles, and to analyze the correlation between FGV and gestation age. Methods A total of 157 healthy pregnant women underwent prenatal screening were included. The reference range of FGV was measured with three-dimensional ultrasonic VOCAL at 30°, 18° and 12° rotation angle, respectively. The correlation between FGV and gestation age was observed, and the consistency of FGV values measured with VOCAL at different rotation step angles was compared. Results The correlations between FGV values measured with VOCAL at 30°, 18°, 12° rotation step angles and gestation age were all excellent (r=0.92, 0.88, 0.90; all P<0.001). The consistency of FGV values measured with VOCAL at different rotation step angles was very good (30° and 18°, ICC=0.94; 30° and 12°, ICC=0.97; 18° and 12°, ICC=0.94). Conclusion Three-dimensional ultrasonic VOCAL can be used to establish the reference range of fetal gallbladder volume in middle-late pregnancy. The consistency of FGV values measured with VOCAL at different rotation step angles was very good, and the correlation between FGV and gestation age was excellent. |
