WEB BASED DATA MANAGEMENT FOR OBSTETRIC ULTRASOUND

流行病学，统计和预防研究部要求正常胎儿生长的超声标准，包括不同种族/民族的妇女，非裔美国人，亚裔，西班牙裔和白人。还需要双胞胎胎儿生长轨迹的数据，特别是绒毛线性数据。这项队列研究名为“胎儿正常生长国家标准”，招募了2400名低风险孕妇和600名肥胖的单胎孕妇。研究地点包括西北大学、南卡罗来纳医科大学、加州大学、罗德岛妇幼医院。获得了58.5万张单独的超声图像。收集和研究了宫内生长受限新生儿的胎盘。

The Division of Epidemiology, Statistics, and Prevention Research requests ultrasound standards for normal fetal growth that includes racially/ethnically diverse women, African-American, Asian, Hispanic, and Whites. Data is also needed on fetal growth trajectories for twins, particularly by chorionicity. The cohort study was “The National Standard for Normal Fetal Growth”, which enrolled 2,400 low risk pregnant women and 600 obese pregnant women with singleton. Sites included Northwestern University, Medical University of South Carolina, University of California, Women’s and Infant’s Hospital of Rhode Island. There are 585,000 individual ultrasound images acquired. The placenta of intrauterine growth restricted neonates are collected and studied.
