Cerebral Doppler imaging in neonates: A guide for clinical application and diagnosis

Abstract

Cranial ultrasound reliably diagnoses many neonatal brain disorders. Adding Doppler imaging expands the spectrum by providing information on the status of the vasculature and haemodynamics that may guide further diagnostic and clinical management. Doppler imaging may identify neonates with congenital or acquired vascular abnormalities such as perinatal stroke, sinuvenous thrombosis, vein of Galen malformation, dural sinus malformation, sinus pericranii, and developmental venous anomaly. These entities may need further investigation with complementary imaging modalities such as magnetic resonance imaging and magnetic resonance angiography, or conventional angiography. This review aims to help clinicians to improve their Doppler sonography knowledge and skills in order to use this helpful tool in neonates with neurological symptoms or suspected cerebral vascular abnormalities admitted to the neonatal intensive care unit.
