Cranial ultrasound (US) remains the mainstay of neonatal brain imaging. It is safe and can be performed at the cot side without sedation and with very little disturbance even to very sick infants. Both normal and abnormal US scan have been very useful in predicting neurodevelopmental outcome. Initially cranial US was used to detect hemonhage and ventricular dilatation in preterm infants, but now the emphasis has moved to defining white matter injury, which is more difficult. There are concerns that infants with normal scans do not always have normal neourodevelopmental outcomes. The aim of this work is to evaluate cranial ultrasonography and neurological examination in a cohort of infants regarded as normal; and to determine the prevalence of ultrasound abnormalities and any potential association with antenatal or perinatal factors or deviant neurological signs.
