Previous studies have shown that R2* increases in normal liver after contrast administration. In this work, we investigated the relationship between patients clinical data, including body mass index (BMI) and blood analysis results, and R2* measurement, performed before and after administration of gadoxetic acid. A lack of increase of R2* after contrast administration was correlated with elevated values of both total bilirubin and MELD scores, which are measures of liver function and severity of chronic liver disease.
