Abstract: 【Abstract】〓Objective〓To explore the distribution characteristics of liver function in anatomy. Methods〓Forty-seven patients who underwent EOB-CE-MRI scans were analyzed. They were classified into three groups according to Child-Pugh classification (CPS): normal liver function (NLF) group (n=19), CPS A group (n=15), CPS B group (n=13). Liver-liver Rate of Enhancement (LLRE) method was adopted. Statistical analysis were performed by relevant software. A paired t-test was used to compare the differences between the central and peripheral zones, the right and left lobes, the right anterior and right posterior segments, and the S2 and S3 segments in three groups. Afterwards,the signal of pre-contrast and post-contrast in hepatobiliary phase were compared respectively in three groups. The P<0.05 indicated a significant difference. Results〓The LLRE between the central and peripheral zones was significantly difference (P<0.001) for patients. There were no statistical differences between left and right lobe as well as the S2 and S3 segments (P>0.05)..The mean value of the average signal had no difference in pre-contrast and had significant difference after contrast among different groups (P<0.05). Conclusion〓The liver function in the center of the liver was higher than peripheral zones. The difference between left and the right lobes as well as the S2 and S3 segments were not apparent. The relative enhancement ratio was significantly different among different groups.
