Abstract
Introduction. The past half-century has been marked by rapid advances in digital technologies and their integration into multiple areas of human activity, including medicine. One of the most dynamically evolving fields is volume (three-dimensional) ultrasonography, which offers substantial advantages over conventional 2D-imaging by providing novel insights into the nature and pattern of fetal central nervous system (CNS) anomalies.
Objective. To analyse the scientific literature on the application of volume ultrasonography and subsequent processing of three-dimensional ultrasound data files for the assessment of the fetal CNS during the first trimester of pregnancy.
Materials and Methods. A narrative review was conducted using PubMed, eLibrary, the Cochrane Library, UpToDate, MEDLINE, and Embase for the period 2011–2024. A total of 42 sources were reviewed.
Results. Current data demonstrate the potential of first-trimester ultrasonography for the early detection of fetal CNS anomalies, highlighting the diagnostic capabilities of threedimensional imaging.
Conclusions. Published evidence underscores the relevance and clinical value of volume ultrasonography, particularly the subsequent utilisation of three-dimensional ultrasound data files, for the investigation of the fetal CNS in the first trimester of pregnancy.
