2025 Scholars' Research Symposium Abstract: Ultrasonographic Accuracy in Rural vs Urban Counties.

This study showed no statistically significant differences between ultrasonography performed in rural vs urban counties, in the second trimester, regarding the accuracy for newborn weight prediction or detection rate of congenital anomalies within our single health system. To the author's knowledge, this is the first study to investigate disparities in ultrasonography accuracy across U.S. rural and urban communities. Enhanced understanding of how potential sources of error, including patient volume, specialized expertise of the ultrasonographer, and equipment, is needed to improve prenatal assessment reliability for informed decision-making and ultimately maternofetal outcomes in rural communities. Future work should seek to expand the sample sizes to further stratify the population groups and control for ultrasound equipment, ultrasonographer, and who read the scans.
