By this time, we should expect that the ultrasonic diagnosis of periventricular hemorrhage should be definitive with demonstration of an echodense patch in an ependymal region that deforms the adjacent ventricular contour in its early stages (Fig 1). The combined experience with transfontanel viewing, which has spanned some four generations of ultrasonic equipment, convincingly demonstrates that the selection and operation of an instrument can have a profound effect on the diagnosis of acute neonatal intracranial pathology.
Visualizing intracranial hemorrhage is primarily a contrast or "gray scale" resolution task, not a matter of spatial or detail resolution.
