Ultrasound screening in a neonatal unit.

Ultrasound (US) is an important imaging tool for evaluating the neonate. US is portable and non-invasive and can be repeated as often as is necessary. It is therefore the imaging modality of choice for imaging the critically ill neonate. The quality of US and its diagnostic accuracy depends on many factors; suitable equipment with appropriate settings and probes, scanning at appropriate times and the experience and expertise of the examiners.1 This is a brief review of the typical US imaging findings encountered in a neonatal unit.
