The relation of liver fat content to CT number was studied in 20 rabbits (17 experimental, 3 control), where fatty degeneration was produced by carbon tetrachloride (CCl4) ingestion. Liver scanning was performed before and 2--5 days after CCl4 administration.. Changes (decrease) in CT number were compared with triglyceride (TG), water, and protein content of resected livers. A decrease of 12--20 CT numbers (24--40 H) reflected a TG concentration of 20--40 mg/g.
在20只兔子（17只实验兔，3只对照兔）身上研究了肝脏脂肪含量与CT值的关系，通过摄入四氯化碳（CCl4）诱导脂肪变性。在给予CCl4之前以及之后2至5天进行肝脏扫描。将CT值的变化（降低）与切除肝脏的甘油三酯（TG）、水和蛋白质含量进行比较。CT值降低12至20（24至40 H）反映甘油三酯浓度为20至40 mg/g。
