The fetal limb volume reflects the nutritional status and intra-uterine growth of the fetus. The arrival of the three-dimensional ultrasound has allowed a more accurate volumetric evaluation of irregularly shaped structures such as fetal organs. The three-dimensional multiplanar mode is the most efficient technique to evaluate fetal limb volume as a parameter for a more accurate birth weight prediction. Currently, this method is useful for monitoring the development of soft tissue and for early detection of fetal growth deviations. In our country, where fetal growth restriction is frequent, with poor access to a skilled neonatal assistance, the dissemination of this technique could definitely contribute to reduce the rates of perinatal morbidity and mortality.
