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

Abstract
Intracranial hemorrhage (ICH), specifically hemorrhage in the subependymal germinal matrix, is a common disorder affecting human preterm neonates. Relative virtues and limitations of portable real-time ultrasonography (US) and computed tomography (CT) in detection and follow-up of sequelae of this disorder are discussed. The importance of cooperation among the radiologist-ultrasonologist, neonatologist, pediatric neurologist, neurosurgeon and ultrasound technologist is emphasized.
