Normal Range of the Length of the Fetal Corpus Callosum in the Second Trimester of Pregnancy
Abstract
Purpose. To develop the reference range length of the fetal corpus callosum in 18-27 weeks of gestation. Materials and methods. Fetal brain was evaluated in 292 normal fetuses at 18-27 weeks of gestation. The multiplanar mode to obtain the mid-sagittal plane and measured length of the fetal corpus callosum. The length of the corpus callosum was measured from the most anterior aspect of the genu to the most posterior aspect of the splenium. Results. In 98% satisfactory visualization and measurements of the corpus callosum were obtained. Length of the corpus callosum is increasing during the second trimester of pregnancy. Normal range plotted on the reference range (mean, 5th and 95th percentiles) of length of the corpus callosum. Conclusion. Measurement of the length of the corpus callosum may be useful for assessment development of the corpus callosum in cases of suspicion on cerebral anomalies like hypoplasia, partial agenesis of the corpus callosum.
