目的：评价肚脐平面腹部脂肪比率(AFR,脂肪容积占腹部总容积的比率)对肝脏 CT 强化程度的影响。方法本研究从存档数据库中收集87例患者的临床资料,其中男47例,女40例。肝脏最高强化程度用对比剂剂量、体重进行调整后(aMHE,肝脏最高强化程度除以每公斤体重使用的对比剂剂量),应用 Pearson 相关及线性回归分析不同性别患者的平均年龄和 AFR 对 aM-HE 的影响。结果在男性及女性组,aMHE 与患者 AFR 均呈正相关(r 分别为0.48、0.46,P 值均<0.01)；aMHE 与患者年龄均无显著相关性。结论腹部脂肪比率与肝脏强化程度正相关,表明腹部脂肪含量高的患者需要相对较少的对比剂剂量即可获得与腹部脂肪含量少的患者一致的肝脏强化程度。

Objective To evaluate the effect of abdominal fat ratio (AFR,abdominal fat volume to total abdominal volume)at the umbilical level on hepatic CT enhancement in humans.Methods We analyzed data in 87 patients (40 women and 47 men)by Pearson correlation and linear regression analysis to assess the association of patient age and AFR with adjusted maximal hepatic enhancement (aMHE,maximal hepatic enhancement divided by the dose of iodine divided by body weight)by sex.Results aMHE was positively correlated with AFR for both men and women (r=0.48 and 0.46,respectively,both P <0.01)but not patient age.Conclusion Pa-tients with more abdominal fat seem to require relatively less amount of contrast media to get the CT enhanced degree of liver similar to those with less fat.
