Enhanced Diagnostic Capabilities: Ultrasound Imaging of Fetal Alimentary Tract Obstruction with Advanced Imaging Technologies.

BACKGROUND Congenital malformations of the alimentary tract constitute 5% to 6% of newborn anomalies, with congenital intestinal atresia being a common cause of alimentary tract obstruction. This study explores advanced ultrasound diagnostic possibilities, including 2D, HDlive, HDlive inversion, and HDlive silhouette imaging modes, through the analysis of 3 cases involving duodenal and intestinal obstructions. Congenital malformations of the alimentary tract often present challenges in prenatal diagnosis.
