Basic examination of the fetal brain includes the evaluation of low risk pregnancies with three axial planes commonly referred to as the transventricular plane, the transcerebellar plane and transthalamic plane. The detailed evaluation (fetal neurosonogram) of the fetal CNS is useful in the evaluation of an increased risk of CNS anomalies including cases in which the basic examination identifies suspicious findings . However, this examination requires a grade of expertise and sophisticated ultrasound system.
A semi-automated technology, 5D CNS+ of WS80A with Elite, provides nine planes (axial, coronal, sagittal planes) of fetal brain and biometric measurments. Especially, in addition of sagittal and coronal planes in the screening evaluation of fetal CNS anatomy, 5D CNS+ helps to improve the diagnostic efficacy and provide capability of diagnosing anomalies of the midline and posterior fossa which cannot be seen by the axial planes. 5D CNS+ will give further benefits on prenatal diagnosis management and prognosis of fetal central nervous system.
