CEREBRAL DOPPLER STUDIES IN PEDIATRICS

The overwhelming majority of neuropathologic processes associated with perinatal Insults are related to cerebral blood flow alterations. It follows that structural ultrasonography is not sufficient and that pul sed Doppler and color flow Doppler studies should be done to gather he modynamic data. These ''active ultrasonogram studies'' can suggest an early diagnosis (hemorrhage, ischemia), provide accurate, immediate pr ognostic information (ischemia, hydrocephalus), and, in some instances , lead to preventive therapy (hemorrhage).
