Over an insignificant five years, neonatal cranial sonography has advanced from an vague and mostly experimental imaging hazard to the modality of choice within the exam of the younger mind. the just about instant attractiveness of the ultrasound exam of the neonatal mind used to be according to a few coinci dent components, an important of which used to be the emergence of a burgeoning inhabitants of untimely neonates who have been, for the 1st time, surviving be yond infancy. those soft sufferers have been starting to stand up to the pains of extrauterine lifestyles whilst now not totally ready for it; pulmonary, cardiac, and infec tious illnesses not claimed so much of them. With survival, a brand new specter reared its head: could the eventual psychological and neurologic prestige of those comparable young ones be definitely worth the cost and time had to carry them via their first months? This factor grew to become more and more urgent as proof fastened during the Seventies that very untimely neonates have been at a excessive probability for intracranial hemor rhage and posthemorrhagic problems. An imaging modality that can overview the untimely mind was once sorely wanted. The CT scanner with its confirmed skill to diagnose intracranial hemorrhage used to be of little price during this regard. So too have been static gray-scale or waterpath ultrasound devices. those modalities all had an identical problem, loss of portability. As neonatal extensive care devices proliferated, so did the know-how that will quickly let cribside neonatal neuroimaging, the real-time area scanner.

One rarely finds significant cerebroventricular hemorrhage (CVH) in neonates who are more than 32 weeks gestational age. 7- 11 A specific demarcation between term and premature is of great importance; all premature neonates should undergo at least two cranial sonograms. Such routine and intensive scanning is costly and time consuming, and is not warranted for neonates who are not at a high risk for intracranial pathology. Many authors have used birthweight as the determining factor in their scanning routines I2- 14 ; we feel this is not optimal.
