Successful visualization in the coronal and sagittal planes was significantly correlated with that of a control population (<jats:italic>r<\/jats:italic> = 0.615; 95% CI, 0.390\u20130.771). In 20\/21 fetuses at least one observation was adequate for analysis. Eleven cerebral abnormalities were found in nine fetuses, periventricular echodensities in four, intraventricular hemorrhage in two, and localized thalamic densities in five. In six of these infants ultrasound abnormalities persisted after birth. Neurological follow\u2010up at 24 months demonstrated abnormalities in three infants, two infants were normal and one was lost to follow\u2010up. The three infants with normal ultrasound results after birth had a normal follow\u2010up. Five infants with normal antenatal ultrasound results showed ultrasound abnormalities during the neonatal period; four of them developed PVL Grade 1 and one developed PVL Grade 2. The follow\u2010up of two of these infants was normal, two died and one developed spastic tetraplegia. Abnormal antenatal brain sonography was significantly correlated with gestational age at birth (<jats:italic>r<\/jats:italic> = 0.487; <jats:italic>P<\/jats:italic> = 0.029).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Peri\u2010 and intraventricular echodensities can be detected reliably before birth in fetuses at high risk for uteroplacental insufficiency.
