The Brain

ABSTRACT The corpus callosum is the main commissure of the fetal brain and can be displayed with two-dimensional (2D) and threedimensional (3D) ultrasound. However, only 3D ultrasound provides the operator with the possibility to adjust the three orthogonal planes of the brain in that way that the entire corpus callosum is shown precisely in the median plane. The aim of this article is to provide the most recent information on the assessment of the fetal corpus callosum by means of 3D ultrasound. Different topics are highlighted, such as advantage of 3D ultrasound over 2D ultrasound, indications for displaying the fetal corpus callosum, demonstration of the normal and abnormal corpus callosum and biometric measurements of the fetal corpus callosum by 3D ultrasound. Furthermore the question is raised whether fetal magnetic resonance imaging (MRI) can give additional information to the 3D ultrasound examination and whether the diagnosis resulting from 3D neurosonography gives us the chance for a better counseling of parents who are confronted with the diagnosis of a fetal corpus callosum pathology.

Cns Anomalies

ABSTRACT Central nervous system (CNS) malformations are some of the most comon congenital abnormalities. Long-term follow-up studies suggest that the incidence may be as high as 1 in 100 births. Imaging technologies have been remarkably improved and contributed to prenatal evaluation of fetal CNS development and assessment of CNS abnormalities. The routine examination of the fetal brain can be achieved with axial planes by conventional transabdominal ultrasonography. In order to provide a complete view of the different brain structures a detailed fetal neurosonogram requires additional coronal and sagittal views. Three-dimensional (3D) sonography should be performed transvaginally using the multiplanar approach. Transvaginal high-resolution 3D ultrasound can demonstrate cerebral fine vascular anatomy such as medullary vessels, intracranial calcification, vascular abnormalities. Parallel slicing provides a tomographic visualization of internal morphology similar to magnetic resonance imaging (MRI). Fetal MRI appears to be a useful adjunct to ultrasound to confirm or exclude certain abnormalities. MRI is a valuable complementary tool to detailed neurosonography which allows an evaluation of the normal brain maturation from the second trimester. It also offers a higher diagnostic performance for some congenital abnormalities such as cortical development or posterior fossa assessment.

ABSTRACT Transvaginal high-resolution ultrasound and three-dimensional (3D) ultrasound have been establishing sonoembryology as well as neurosonography in the first trimester. Fetal brain is rapidly developing and changing its appearance week by week during pregnancy. The most important organ, but it is quite hard to observe detailed structure of this organ by conventional transabdominal sonography. It is possible to observe the whole brain structure by magnetic resonance imaging in the post half of pregnancy, but it is difficult in the first half gestation, and transvaginal high-resolution 3D ultrasound is the most powerful modality. As for brain vascularization, main arteries and veins have been demonstrated and evaluated in various CNS conditions. Transvaginal high-resolution 3D ultrasound can demonstrate cerebral fine vascular anatomy, such as medullary vessels and it is greatly expected to estimate neurological prognosis relating with vascular development during fetal period.

Abstract Objective To analyze the interobserver and intraobserver reproducibility of the visualization and continuity of the juncional zone (JZ) by three-dimensional (3D) ultrasound in infertile women, and to evaluate the sociodemographic, hormonal, and structural factors that influence these assessments. Methods A prospective study conducted at the Assisted Reproductive Technology Unit of Hospital Senhora da Oliveira, in the city of Guimarães, Portugal. Transvaginal 3D ultrasonography was performed, and 2 volumes were generated per case. Two observers who were blinded to each other's work analyzed these volumes, choosing the best coronal section. Four months later, one of the observers performed the same methodology. The JZ visualization was classified as optimal, satisfactory, and unsatisfactory, and the JZ continuity, as continuous and discontinuous. The interobserver and intraobserver agreements were analyzed. The influence of hormonal, structural, and sociodemographic factors on the JZ was evaluated. Results In total, 65 women were included in the present study. The interobserver reproducibility was substantial for JZ visualization and continuity (k = 0.635 and 0.753 respectively), and the intraobserver reproducibility was very good for JZ visualization and continuity (k = 0.884 and 0.816 respectively). Trilaminar endometrial pattern was associated with optimal JZ visualization (p = 0.012). The increase of 1 unit in the level of serum estradiol represents a 9.9% decrease in the odds of unsatisfactory visualization of the JZ (odds ratio [OR] = 0.9; 95% confidence interval [95%CI] = 0.814–0.996; p = 0.042). Endometriosis increases the odds of unsatisfactory visualization by 24 times (OR = 23.7; 95%CI = 1.262–437.057; p = 0.034). The prevalence of discontinuous JZs was of 60%. Myomas and endometriosis were associated with discontinuous JZs (p = 0.034 and 0.016 respectively). Conclusion The assessment of JZ visualization and continuity by 3D ultrasound is reproducible enough to be used in the clinical practice.
