“…The volumes can also be sent to tertiary centers for analysis ( 20 , 21 ) . Additionally, the utilization of the Ref slice key allows for the acquisition of the exact measurement plane ( 22 ) , which is a difficulty observed at conventional 2DUS. As the cisterna magna, particularly in the second trimester, is a small and relatively regular structure, the ellipsoid 2D method could also be an alternative to 3DUS and magnetic resonance imaging (MRI).…”

ObjectiveTo establish reference intervals for the fetal cisterna magna volume by means of two-dimensional (2D) method using the multiplanar mode of three-dimensional ultrasonography.Materials and MethodsCross-sectional study with 224 healthy pregnant women between the 17th and 29th gestational weeks. The volume was automatically obtained by multiplying the three major axes in axial and sagittal planes by the constant 0.52. Polynomial regression was utilized to establish the correlation between fetal cisterna magna volume and gestational age, with adjustments by coefficient of determination (R2). Reliability and agreement were obtained by intraclass correlation coefficient (ICC) and limits of agreement, respectively.ResultsMean fetal cisterna volume with the 2D method ranged from 0.71 ± 0.19 cm3 to 4.18 ± 0.75 cm3 at the 17th and 29th weeks, respectively. The authors observed a good correlation between fetal cisterna magna volume and gestational age (R2 = 0.67), excellent intraobserver reliability and agreement with ICC = 0.89 and limits of agreement 95% (-52.0; 51.8), respectively, and low interobserver reliability and agreement with ICC = 0.64 and limits of agreement 95% (-110.1; 84.6), respectively.ConclusionReference intervals for fetal cisterna magna volume by means of 2D method using the multiplanar mode of three-dimensional ultrasonography were established and presented excellent intraobserver reliability and agreement.

“…Furthermore, all cases were evaluated for indirect signs of agenesis of the corpus callosum: widened interhemispheric fissure, upward displacement of the third ventricle, radial arrangement of the medial gyri, asymmetrical enlargement of the lateral ventricles, and teardrop configuration of the lateral ventricles [9]. In cases of abnormal corpus callosum length or thickness, the length, height, and area of the corpus callosum were recorded and compared with normal growth charts [14,15].…”

“…27,28 The presence of a normal CC and its biometry has been assessed by transabdominal and transvaginal 2D and 3D sonography and with fetal MR imaging from 18 weeks onward. 10,17,[29][30][31][32][33] Indirect appreciation of the developing CC will be seen by demonstration of the pericallosal artery and its branches. Recently, color Doppler mapping documented the modified arterial vascular supply with loss of the semicircular loop in CC agenesis (Fig 12).…”

BACKGROUND AND PURPOSE:Anomalies of the corpus callosum are rare. Routine scanning in midtrimester of the pregnancy often fails to identify defective development. The purpose of the study was to identify the pericallosal artery and all its main branching arteries during early gestation from the first trimester onward, to measure the length of the pericallosal artery during its development, and to establish a normal vascular map for each week of development.
