Quantitative Evaluation of Hepatic Microvascular Perfusion after Ischemia –Reperfusion Injury in Rabbits by Contrast-Enhanced Ultrasound Perfusion Imaging

The aim of this study was to evaluate microvascular perfusion after liver ischemia –reperfusion injury (IRI) in rabbits using the “flash-replenishment” method of contrast-enhanced ultrasound (CEUS) perfusion imaging. Twenty-eight rabbits underwent either 30, 60 or 90 min of ischemia and 120 min of reperfusion. CEUS perfusion imaging was performed using the “flash-reple nishment” model, and hepatic microvascular perfusion parameters, including peak intensity (PI), area under the curve (AUC), and hepatic artery-to-vein transit time (HA-HVTT), were calculated.
