Abstract:: Abstract: Objective To analyze the application value of three-dimensional ultrasound in the assessment of the development of fetal spinal cord and spine, thereby providing a diagnostic basis for prenatal fetal malformation screening. Methods The three-dimensional volumetric data of 41 222 pregnant women, including 40 281 singleton pregnant women and 941 twin-pregnant women, who underwent three-dimensional ultrasound examination in the Second Nanning Peoples Hospital from July 2012 to April 2020 were obtained. The detection rates of ultrasound in developmental anomalies of spinal cord and spine were statistically analyzed. Results Of the 41 222 pregnant women, 82 had developmental anomalies of fetal spinal cord and spine which were confirmed by induced labor or postpartum MRI and ultrasound. A total of 77 cases with developmental anomalies were found by three-dimensional ultrasound. Conclusion Three-dimensional ultrasound can accurately assess the development of fetal spinal cord and spine, with a high screening rate of developmental anomalies, which can provide a diagnostic basis for prenatal diagnosis and clinical management.
