Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of our study is to determine the range of frontal horn sizes (both upside and downside) in healthy fetuses over gestation and to determine how far FHs are from the midline . Also to determine the range of cavum septi pellucidi and Corpus callosum sizes . Also, to determine whether the maternal body mass index (BMI) affects rates of visualized and non-visualized CSP and CC.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Fetal central nervous system (CNS) abnormalities are among the most commonly encountered congenital abnormalities . Many different methods can be used to obtain prenatal diagnoses, including ultrasound (US), which is one of the most commonly used methods .Neonatal survival rates have increased over the last decades leading to increased number of infants with adverse neurodevelopmental outcomes, including cognitive, motor impairments and behavioral and learning difficulties later in life . Recent studies demonstrated that signs of abnormal neurological development are already present at birth .

Frontal horns (FHs) are the most anterior portions of the lateral ventricles, on each side the cavum septi pellucidi (CSP). In accordance with practice parameters released as early as 1985 by the American Institute of Ultrasound in Medicine, American College of Obstetrics and Gynecology, and Society of Radiologists in Ultrasound, the CSP is examined in screening fetal ultrasound (US) examinations in the biparietal diameter view . Frontal horns (FH) are also visualized in the same plane. Abnormal morphologic characteristics of the FHs such as enlargement, squaring, spearing, and splaying may have an association with congenital intracranial anomalies such as holoprosencephaly, schizencephaly and agenesis of the corpus callosum .

The corpus callosum (CC) is the largest interhemispheric white matter commissure of the human brain . It is a sensitive indicator of normal brain development and maturation

Ultrasound

Gestational age, biparietal diameter and head circumference are measured. then 2 techniques are used according to the 2007 International Society of Ultrasound in Obstetrics and Gynecology guidelines for a US evaluation of the fetal central nervous system (CNS) (10) : 1- the axial transventricular technique including the posterior portions of the lateral ventricles, falx, CSP, and Frontal horn 2- the trans-cerebellar technique, including the cerebellum, cisternal magna, cerebellar peduncles, CSP, and FHs. CSP visualization and width, FH width, anterior horn width (AHW), center from the horn distance (CFHD), upside and downside measurement.

The corpus callosum is identified in the midsagittal plane. The image selected for CC measurement in addition to cerebellar vermis and cisterna magna
