ABSTRACT

Objective:To investigate the clinical value of Omniview combined with volume contrast imaging (VCI) in measuring the posterior angle of fetal near-field lateral ventricle.Methods:Fifty fetuses whose lateral ventricles were widened, corpus callosum was poorly developed, and who had hydrocephalus as indicated by routine ultrasonography performed between October 1, 2018 and December 31, 2019 in Hangzhou Obstetrics & Gynecology Hospital were included in this study. The width of the posterior angle of fetal near-field lateral ventricle was measured using routine ultrasonography, Omniview-VCI technique, and magnetic resonance imaging (MRI) in each fetus and compared among the three techniques.Results:The width of the posterior angle of fetal near-field lateral ventricle measured by Omniview-VCI and MRI techniques was (1.17 ± 0.15) cm and (1.20 ± 0.12) cm, respectively, which was significantly greater than that measured by routine ultrasonography [(1.11 ± 0.13) cm, t = 2.137, 3.597, both P < 0.05]. There was no significant difference in the width of the posterior angle of fetal near-field lateral ventricle measured by Omniview-VCI technique versus MRI technique ( t = 1.104, P > 0.05). The mean examination cost and waiting time of Omniview-VCI technique were (222.15 ± 3.20) yuan and (0.24 ± 0.04) days, which were less or shorter than those of MRI technique [(597.23 ± 11.02) yuan, (1.02 ± 0.10) days, t = 213.126, 51.210, both P < 0.05]. Conclusion:Omniview-VCI technique can replace MRI and accurately measure the posterior angle of fetal near-field lateral ventricle. It provides a more simple, fast and effective method for evaluating fetal near-field lateral ventricle, and can become a conventional application technique.
