PY - 2023 T2 - Timor's Ultrasonography of the Prenatal Brain, 4e AB - KEY POINTSSonographic evaluation of the fetal vertebral column is considered an integral part of the routine second-trimester ultrasound examination.Starting early in pregnancy it is possible, in selected cases, to ascertain some vertebral anomalies. Still, some of these anomalies can remain undiagnosed even later.3D ultrasound is increasingly used and has become instrumental in imaging the vertebral column in the three orthogonal planes using the x-ray or maximum mode rendering.MRI may at times be necessary to complete the workup.
