Simple linear regression models of rrT1_in and rrT1_W on ¹³C-MBT values.

rrT1_in: reduction rate of T1 relaxation time using in-phase T1 mapping.

rrT1_W: reduction rate of T1 relaxation time using water-only T1 mapping.

¹³C-MBT: liver function capacity estimated by breath analysis of ¹³C-labeled methacetin metabolism.

r: multiple correlation coefficient.

B: linear regression coefficient.

CI: confidence interval for B.
