Infant skulls do not provide the severe barrier to ultrasound diagnosis that the adult skull does. Improved ultrasound instrumentation has made it possible to visualize the brains of infants and small children in detail, through the intact skull, non-invasively and non-accumulatively. This has decreased the hesitancy of physicians to request diagnostic brain studies on seriously ill babies, particularly premature and neonatal ones. The ability to provide considerable diagnostic information in children through age 3 1/2 or 4 years, when diploe start to appear in the parietal bones, adds to the usefulness of two-dimensional ultrasound brain visualization. |
