This study explores the efficacy of 3D color flow (3DVF) in measuring blood flow to the brain under various physiological conditions, including severe traumatic brain injury and hemorrhagic shock, using a cohort of 7 Yorkshire mix pigs. The research aims to determine if 3DVF can provide accurate quantitative volumetric blood flow measurements compared to traditional invasive flow meters. The experiment simulated six distinct physiological states and found that 3DVF estimated blood flow with a bias of -9.6% relative to the invasive flow meter, demonstrating no significant error even during flow reversal phases. This suggests that 3DVF could potentially offer a more specific biomarker for cerebral hemodynamics than current surrogate markers, with implications for improving critical care monitoring. The study highlights the potential of 3DVF in accurately measuring blood flow to the brain under traumatic conditions, offering a promising tool for clinical settings.
