The role of sonography and the radiologist-ultrasonologist in the detection and follow-up of intracranial hemorrhage in the preterm neonate.

Intracranial hemorrhage (ICH), specifically hemorrhage in the subependymal germinal matrix, is a common disorder affecting preterm neonates. The authors discuss the relative virtues and limitations of portable, real-time ultrasonography (US) and computed tomography (CT) in detection and follow-up of sequelae of this disorder. The importance of cooperative effort on the part of the radiologist-ultrasonologist, neonatologist, pediatric neurologist, neurosurgeon and ultrasound technologist is emphasized.
