Frontiers of Medicine 2012, Volume 6, Issue 4,   Pages 421-427 doi: 10.1007/s11684-012-0223-5

Abstract: volumetry in cirrhosis and acute liver failure (ALF) patients, we explored the correlation between hepatic volumeto get a regression formula for standard liver volume (SLV) and BSA.It turned out that the mean liver volume of the control group was 1 058±337 cm3.The hepatic volume of cirrhosis patients in Child A, B level was not reduced, but in Child C level itwas significantly reduced with the lowest liver volume index (CTLV/SLV).
