Quantitative CT assessment for hepatic steatosis / 中华普通外科杂志

ABSTRACT

Objective To evaluate the role of CT in quantitative assessment for hepatic steatosis.Methods We retrospectively assessed 215 liver grafts used in orthotopic liver transplantation (LT) from January 2006 to December 2009.Pathology and CT data were reviewed.The correlation between liver steatosis level and CT value of the liver were analyzed.The ratio of liver-spleen,liver-descending aorta,liver-inferior vena cava were calculated. Results There were 52 steatosis grafts diagnosed by pathologist and the steatosis level was from 2.78％ to 56.8％.The CT value of the liver,the ratio of liver-spleen,liverdescending aorta,liver-inferior vena cava was 41.3 ± 7.5 HU,0.89 ± 0.16,1.02 ± 0.16,1.04 ± 0.15,respectively.There were significant linear negative correlation between the steatosis level and the CT value,the ratio of liver-spleen,liver-descending aorta and liver-inferior vena cava. The correlation index was -0.881,-0.817,-0.951 and -0.948,respectively. Conclusions The CT value of the liver,the ratio of liver-spleen,liver-descending aorta and liver-inferior vena cava could be used to quantitatively evaluate liver steatosis.The ratio of liver-descending aorta was the most sensitive index.
