The value of transfontanellar ultrasound in infants.

We report here our experiences over the past two years of using transfontanellar ultrasound to image the infant brain. A consecutive series of 15 examinations has been analysed retrospectively, with particular reference to the clinical indications and accuracy of the technique. Correlation with computed tomography (CT) has been found to be excellent, and the availability of ultrasound has led to a reduction in the proportion of patients receiving CT scans. Ultrasound has directly influenced clinical management and has emerged as the primary imaging procedure for the brain in infants under three months of age.
