Ultrasound methodology used to construct the fetal growth standards in the INTERGROWTH-21st Project
Abstract
A unified protocol is essential to ensure that fetal ultrasound measurements taken in multicentre research studies are accurate and reproducible. This paper describes the methodology used to take two-dimensional, ultrasound measurements in the longitudinal, fetal growth component of the INTERGROWTH-21(st) Project. These standardised methods should minimise the systematic errors associated with pooling data from different study sites. They represent a model for carrying out similar research studies in the future.
Keywords: Fetal biometry; INTERGROWTH-21st; fetal growth; standards; ultrasound.
