Background. The study of resistances of the uterine and umbilical arteries represents the principal method for the prediction and diagnosis of adverse pregnancy outcomes such as preeclampsia (PE) and intra-uterine growth restriction (IUGR). Three-Dimensional (3D) power Doppler allows a quantification of vascularization by calculating the Vascularization index, Flow Index and Vascularization Flow Index (VI, FI and VFI). Objective.

Introduction
Fetal femur length below the expected value has been described as a marker of aneuploidy, skeletal dysplasia, intrauterine growth restriction and small‐for‐gestational‐age neonate. The aim of this systematic review and meta‐analysis was to evaluate the strength of association between isolated short femur length and intrauterine growth restriction or small‐for‐gestational‐age, and perinatal adverse outcomes.
