Blood oxygen level-dependent MRI for evaluation of early response of liver tumors to chemoembolization: an animal study.


AIM To evaluate the feasibility of carbogen-challenge blood oxygen level-dependent (BOLD) magnetic resonance imaging (MRI) for assessing the early response of liver tumors to chemoembolization in a rat hepatoma model. MATERIALS AND METHODS In a 9.4-Tesla scanner, a multiple gradient-recalled echo sequence was utilized for R2* measurement at 11 and 13 days… (More)
