Multiparametric magnetic resonance imaging (MRI) provides various noninvasive and quantitative diagnostic information. This study assessed the value of multiparametric MRI in liver regeneration after warm ischemic-reperfusion injury (WIRI) in a rabbit model with different warm ischemia and reperfusion times. The results showed that the tissue diffusivity (Dslow), pseudo-diffusion coefficient (Dfast), perfusion fraction (PF), apparent diffusion coefficient (ADC), fractional anisotropy (FA), and R2* maps reflected changes in hepatic microcirculation perfusion, micro-dispersion, and oxygenation of hepatic WIRI after partial hepatectomy. Liver regeneration capacities were enhanced when warm ischemia times were 30 minutes or less; however, they were diminished after 30 minutes.
