A comparision of linear-array and mechanical-sector cranial ultrasound scanning techniques to predict neurodevelopmental outcome at 8 years in preterm newborn infants.
Two methods of neonatal cranial ultrasound (US) scanning, linear-array and mechanical-sector, were compared for their accuracy in predicting neurodevelopmental outcome in a cohort of 854, of whom 782 (92%) infants, all born less than 33 weeks of gestation and cared for on the Neonatal Intensive Care Unit at University College Hospital, London between 1979 and 1988, were included in the analysis. A total of 205 infants were studied by linear-array and 577 infants by mechanical-sector scan. Ultrasound findings were grouped into three risk categories on the basis of the US diagnosis. Outcome was assessed at 8 years of age. The probability estimates for neurologically disabling and nondisabling impairments, extra education and mean IQ were compared for the two US methods. There was no significant difference between the two methods in the accuracy of prediction of neurodevelopmental outcome.
