Abstract
Contrast-enhanced ultrasound (CEUS) is a valuable bedside imaging technique that enables both qualitative and quantitative assessment of cerebral perfusion. In neonates and infants whose fontanelles remain open, the technique is particularly useful as it delineates cerebral pathology with high soft-tissue contrast. The technique has the potential to be a valuable alternative to computed tomography (CT) or magnetic resonance imaging (MRI) in critically ill neonates and infants in need of bedside imaging. While further studies are needed to validate the technique, preliminary data in this regard appear promising. This review introduces the current understanding and future potential of brain CEUS.
