Birth‐weight prediction by two‐ and three‐dimensional ultrasound imaging

Abstract: Objectives To compare the accuracies of birth-weight predicting models derived from two-dimensional (2D) ultrasound parameters and from total fetal thigh volumes measured by three-dimensional (3D)

“…The present study also showed improved accuracy (MPE −2.542 [2D] to 0.790 [3D]) when using a population‐specific formula as compared the 2D formula of Lee et al . By contrast, Bennini et al . found that, whereas formulas derived from the population served to improve the accuracy, customization of other formulas did not help.…”

“…A principal questão levantada neste estudo foi a maioria dos intervalos de referência para crescimento fetal publicados até o momento ter utilizado fórmulas para estimativa de peso que não eram específicas para a população estudada [4][5][6][7][8] . Nós demonstramos previamente que, independentemente do método utilizado para a estimativa do peso fetal, fórmulas deveriam ser adaptadas às diferentes populações 15 . Na presente análise, o erro sistemático obtido usando nosso modelo (0,74%) foi significativamente menor do que aqueles obtidos utilizado as fórmulas de Hadlock et al 9 (-1,17%; p<0,001), Birnholz et al…”

“…Muitos estudos salientam que os modelos para estimativa de peso fetal deveriam ser adaptados às diferentes populações, respeitando suas características étnicas [9][10][11][12][13][14][15] . No entanto, a maioria dos centros utiliza fórmulas tradicionais geradas em outros países, que podem levar a erros significativos quando aplicadas localmente 14,15 .…”
