What is the role of head ultrasound in detecting IVH in very preterm infants, and at what intervals is it typically performed?

• A. MRI within the first week and CT every few days.
• B. Used to screen for IVH; commonly performed in the first week of life (day 1, day 7) and then as indicated by risk.
• C. CT scans weekly for IVH screening.
• D. Head ultrasound is not used in this population.

Answer: (B)

Head ultrasound is the go-to screening tool for intraventricular hemorrhage in very preterm infants because it’s safe, bedside-friendly, and can be repeated easily to watch the brain for changes. In practice, you screen during the first week of life, typically with scans around day 1 and again around day 7. After those initial checks, further imaging is guided by the infant’s risk factors and clinical course. This approach allows early detection and monitoring of IVH and potential hydrocephalus without exposing the baby to radiation or requiring transport to an MRI or CT suite.
