Neonatal head ultrasound is a safe, non-invasive imaging test used to evaluate the brain structures of newborns. It is most commonly performed through the soft spot (fontanelle) on a baby’s skull, allowing clear images without radiation. This scan helps detect brain bleeds, hydrocephalus, cysts, and developmental abnormalities in premature or full-term infants. It is especially valuable in neonatal intensive care units for ongoing monitoring of brain health and is a vital tool for early diagnosis and intervention.
