Contrast-enhanced ultrasound for the evaluation of the neonatal brain: Diagnostic methods and scanning protocol

Purpose or Case Report: Contrast-enhanced ultrasound (CEUS) for the evaluation of the neonatal brain provides additional diagnostic information when compared to conventional gray scale ultrasound through the detection of perfusion abnormalities associated with injury. When compared to cross-sectional imaging, CEUS has many advantages given its relative low cost and ability to be performed at the bedside, without the need for sedation or exposure to ionizing radiation. Diagnostic information is yielded through the qualitative evaluation of parenchymal enhancement patterns as well as quantification of microbubble perfusion kinetics from which time intensity curves are derived and additional perfusion parameters can be extrapolated. Given the 2-dimensional nature of the modality, a strategically designed scanning protocol is necessary to obtain the aforementioned quantitative values. The purpose of this exhibit is to demonstrate the current understanding of brain CEUS and educate on the brain CEUS protocol used for the diagnosis of neonatal brain pathology.
