摘　　要：目的:探讨肝硬化背景下小肝癌在动态MR和64排螺旋CT三期扫描中的强化特征。方法:2016年4月-2018年4月收治肝硬化背景下小肝癌患者60例,随机分为两组。研究组采用动态MR检查,对照组采用64排螺旋CT检查。比较两组诊断结果。结果:对照组肿瘤转移率明显低于研究组,对照组局灶性结节性增生及肝硬化结节诊断结果高于研究组,研究组海绵状血管瘤诊断结果显著高于对照组,差异均有统计学意义(P<0.05)。两组肝腺瘤诊断结果比较,差异无统计学意义(P>0.05)。两组扫描诊断HCC病灶,1~3 cm诊断结果比较,差异无统计学意义(P>0.05);而≤1 cm研究组阳性率显著高于对照组,差异有统计学意义(P<0.05)。结论:在临床检查中,动态MR和64排螺旋CT两种检查方法的诊断率高,而动态MR能够准确地诊断出患者病情,能够判断出肿瘤严重程度。Objective:To investigate the enhancement characteristics of small hepatocellular carcinoma in dynamic MR and 64-slice spiral CT three-phase scanning under the background of cirrhosis.Methods:60 patients with small hepatocellular carcinoma under the background of cirrhosis were selected from April 2016 to April 2018,they were randomly divided into the two groups.Dynamic MR was used in the study group and 64 slice spiral CT was used in the control group.We compared the diagnosis results between two groups.Results:The tumor metastasis rate in the control group was significantly lower than that in the study group,and the diagnosis results of focal nodular hyperplasia and cirrhosis nodules in the control group were higher than that in the study group.The diagnosis result of cavernous hemangioma vein in the study group was significantly higher than that in the control group,the differences were statistically significant(P<0.05).There was no significant difference in the diagnosis of hepatic adenoma between the two groups(P>0.05).There was no statistically significant difference between the two groups in the diagnosis of 1 to 3 cm lesions of HCC(P>0.05).The positive rate of the study group≤1 cm was significantly higher than that of the control group,and the difference was statistically significant(P<0.05).Conclusion:In the clinical examination,dynamic MR and 64 slice spiral CT have high diagnostic rate,while dynamic MR can accurately diagnose the patient's condition and judge the severity of the tumor.
