We carried out liver T1rho MR imaging in 10 patients with liver cirrhosis. T1rho value inhomogeneity was noted in the liver of the patients, with T1rho value of right robe tended to be higher than that of left robe. To quantify liver T1rho value, ROIs were manually placed on right robe parenchyma region of each slices T1rho maps, excluding observable artifacts and blood vessels. Nine patients completed the study. With T1rho value measured from the right liver lobes, the mean value ( SD) was 51.18.1 millisecond, higher than the reported T1rho mean value of 43.02.2 millisecond in healthy volunteers.
