Cranial ultrasonography is the most important, accessible, patient friendly, and cheapestneuroimaging technique on the neonatal ward. It provides important information on brain maturation in the (preterm) neonate and enables the detection of frequently occurring brain anomalies. In this this book, the focus is on the basics of the technique, from patient preparation through to screening strategies and the classification of abnormalities. Many new ultrasound images have been included to reflect the improvements in image quality since the first edition. Essential information is provided about both the procedure itself and the normal ultrasound anatomy. Standard technique is described and illustrated, but emphasis is also placed on the value of supplementary acoustic windows.
