متن کاملEvaluation of Nuchal Translucency Measuremen in First Trimester Pregnancy
Background A significant number of pregnancies, particularly in women with previous histories of infertility, are associated with fetal abnormalities. Methods such as the nuchal translucency (NT) measurement enable us to identify more pregnancies with chromosomal abnormalities. MaterialsAndMethods This analytic cross-sectional study was performed in 446 pregnant women at 11-14 weeks gestation, ...
