[Approach by neuroimaging with power flow Doppler imaging]

Area of Science:

• Medical Imaging
• Pediatric Neurology
• Vascular Ultrasound

Context:

• Neonatal intracranial evaluation requires advanced imaging techniques.
• Assessing cerebral hemodynamics in infants is crucial for detecting abnormalities.
• Traditional Doppler sonography has limitations in visualizing small or slow-flowing vessels.

Purpose:

• To introduce and evaluate Power Flow Doppler (PF) imaging for neonatal intracranial applications.
• To demonstrate PF's ability to visualize low-velocity and small-caliber vessels.
• To explore PF's utility in assessing intracranial hemodynamics and arterial pulsation.

Summary:

• Power Flow Doppler (PF) imaging, combined with pulsed Doppler (PD), effectively visualizes small intracranial vessels and slow blood flow, such as the lenticulostriate artery.
• PF imaging allows clear observation of bilateral middle cerebral arteries through the anterior fontanel and evaluation of hemodynamic laterality.
• Four-dimensional PF imaging captures intracranial arterial pulsations, offering a novel approach to quantitative and qualitative intracranial circulation assessment.

Impact:

• PF imaging improves the detection and characterization of intracranial vascular abnormalities in neonates.
• This technique provides a non-invasive method for monitoring neonatal brain hemodynamics.
• The advancements in Doppler sonography offer potential for improved diagnosis and management of neurological conditions in newborns.
