Surface-extraction MRI of the fetal brain: an improved approach for diagnosing anomalies associated with antenatal absence of the septum pellucidum

Introduction

Prenatal imaging is crucial for evaluating neurological development in cases of absence of septum pellucidum (ASP), which may be associated with a spectrum of cortical, cerebellar and ocular anomalies and variable neurodevelopmental outcomes. Recent advances in fetal MRI techniques have improved the detection and characterization of subtle brain abnormalities.
