摘　　要：目的研究肝硬化对肝脏CT增强效果的影响及相关改进措施。材料和方法测定有肝硬化及无肝硬化组在对比剂量分别为1.3、1.6、2.0ml/kg时,肝实质、门静脉和主动脉的CT峰值并进行统计学分析。结果肝硬化组的肝实质强化峰值在对比剂剂量为1.3、1.6及2.0ml/kg时,与对照组有显著差异(P<0.05)。肝硬化组在剂量为1.3、1.6ml/kg时,肝实质增强效果差,当剂量增加至2.0ml/kg时,肝实质的增强效果令人满意。结论肝硬化明显影响肝脏增强效果,有效的改进措施为增加对比剂剂量至2.0ml/kg。Purpose:To investigate the influence of hepatic cirrhosis on hepatic CT enhancement and the related improvement.Materials and Methods:The peak CT values of liver,portal vein and aorta with dose1.3,1.6and2.0ml/kg of contrast material were measured in hepatic cirrhosis groups and contrasted with those of control groups.Results:The peak CT values of hepatic parenchyma with dose of1.3,1.6and2.0ml/kg were significantly different with those of control groups(P<0.05).The hepatic enhancement with dose of1.3and1.6ml/kg couldn’t meet the requirement of diagnosis,when it showed satisfactory hepatic enhancement with increasing dose of contrast material up to2.0ml/kg.Conclusion:Hepatic cirˉrhosis obviously influences hepatic enhancement in contrast CT scanning.The effective improvement is increasing dose of contrast material up to2.0ml/kg.
