This article emphasizes technical factors that are helpful for optimizing sonographic examinations of the brain in preterm and term neonates. It also reviews existing data regarding the accuracy of neurosonographic examinations relative to MR. Many neurosonographic signs are subtle and can be easily overlooked, which could lead to delayed diagnosis or misdiagnosis. ⋯ Although MR images of the brain often depict abnormalities more clearly than sonography, neurosonography continues to be an exceptionally valuable tool for evaluation of the neonatal brain, even in full-term neonates. Furthermore, its accuracy is greater, even in the latter age group, than many older publications suggest. Prospective studies using state-of-the-art equipment comparing findings on sonography and MR are needed to better understand how the accuracy of these modalities changes with refinements in equipment and to help us better understand the role of neurosonography relative to MR.

Pediatric central nervous system (CNS) vascular anomalies include lesions found only in the pediatric population and also the full gamut of vascular lesions found in adults. Pediatric-specific lesions discussed here include infantile hemangioma, vein of Galen malformation and dural sinus malformation. ⋯ The treatment of pediatric CNS vascular malformations has greatly benefited from advances in endovascular therapy, including technical advances in adult interventional neuroradiology. Dramatic advances in therapy are expected to stem from increased understanding of the genetics and vascular biology that underlie pediatric CNS vascular malformations.
