Real-time ultrasonography. Its use in the evaluation of neonatal intracranial hemorrhage and posthemorrhagic hydrocephalus.

We used real-time cranial ultrasonography to diagnose intracranial hemorrhage and to follow the development and resolution of posthemorrhagic hydrocephalus in a premature infant. This technique is a bedside procedure that provides detailed imaging of intracranial pathology in newborn infants, without removing them from their incubators or exposing them to ionizing radiation.
