AbstractBlood oxygenation level-dependent (BOLD) MRI was shown to allow non-invasive observation of renal oxygenation. Experimental bile duct ligation has been widely used as an animal model to evaluate the renal molecular changes. This study aims to investigate the alteration of R2* in the kidney of rat induced by biliary duct ligation. We observed that the medullary R2* in model group is higher than that in controls, but the difference in cortical R2* was not significant between two groups. Our results implicated that acute biliary obstruction induced by bile duct ligation caused an alteration of renal medullar oxygenation. (Abstract by ISMRM)
