Pediatric hydrocephalus is a common disease in the United States, accounting for more than 39,000 annual admissions and a healthcare cost of $1.4-2.0 billion. Timely detection and intervention of intracranial hypertension (ICP), a complication of hydrocephalus, is associated with an improved neurologic outcome. This research aims to evaluate the feasibility of assessing the movement of the floor of the third ventricle and intracranial arterial pulsations on mid sagittal view of the grayscale brain ultrasound for predicting ICP in neonates and infants.

Ultrasound is the first-line screening tool for numerous pediatric pathologies. Its advantages include lack of ionizing radiation, non-invasiveness, real-time dynamic evaluation, and flow assessment capabilities. While conventional Doppler is used for macrovascular evaluation in conditions such as ischemia, infections, and neoplasms, ultrasound microbubble contrast agents allow for more precise perfusion quantification. Microvascular flow imaging (MVI) is a novel technique that employs advanced algorithms for clutter and noise suppression, enabling superior visualization of small vessels and slow-velocity flow without contrast. This technique may reduce the need for contrast-enhanced follow-up studies, except when arterial and venous wash-in and wash-out characteristics are crucial for diagnosis. The utility of MVI in pediatric conditions needs further exploration as this technology is part of ultrasound clinical systems. Read More
