Measurement of the lateral ventricles width by ultrasound investigation in the second trimester of pregnancy

Purpose: to assess reproducibility of measurement of the width of lateral ventricles of the fetal brain by ultrasound investigation in the second trimester of pregnancy. Material and Methods. The volume of the 34 normal fetal brains at 18-21 weeks of gestation was retrospectively evaluated. Two experienced specialists measured the width of lateral ventricles from each fetus twice. Results. Intra-operator differences of the first specialist constituted 0,136±0,065mm, of the second specialist — 0,156±0,066mm. Inter — operator differences counted 0,191±0,062mm. Conclusion. Measurement of the width of lateral ventricles is highly reproducible, it should be performed by ultrasound investigation in the second trimester of pregnancy.
