Cerebral Blood Flow in Term and Preterm Neonates Using Doppler Ultrasonography

This study aims to evaluate cerebral blood flow in stable term and preterm newborns using Doppler ultrasonography. By measuring and comparing PSV, EDV, RI, and PI in the main brain arteries, the study seeks to identify normal physiological differences in cerebral perfusion across different gestational ages. The main goal is to establish reference values that can guide clinical monitoring, allow early detection of blood flow problems, and improve neuroprotective care in newborns.
