分析CT与MRI在介入治疗肝癌后癌肿残留及复发中的早期诊断效果

目的：探讨分析CT与MRI在介入治疗肝癌后癌肿残留及复发中的早期诊断效果。方法：回顾性分析2020年1月～2021年6月在本院治疗的60例原发性肝癌患者的临床资料，共有104个病灶，均行经导管肝动脉化疗栓塞术（TACE）后2～6个月来院复查，进行CT与MRI检查，CT检查为对照组，MRI检查为观察组，以数字减影血管造影（DSA）为金标准，对比两组的诊断结果，诊断的灵敏度、特异度和准确度，肿瘤病灶情况、肿瘤包膜情况。结果：观察组诊断的灵敏度95.24%(60/63)、特异度95.12%(39/41)、准确度95.19%(99/104)，对照组诊断的灵敏度79.37%(50/63)、特异度73.17%(30/41)、准确度76.92%(80/104)，差异有统计学意义（P<0.05）；观察组肝内病灶阳性40例（38.46%）、肝外病灶阳性20例（19.23%）、肝内病灶个数（2.71±0.68）个、肝外病灶个数（2.02±0.57）个，均高于对照组的35例（33.65%）、15例（14.42%）、（2.03±0.70）个、（1.65±0.52）个，差异有统计学意义（P<0.05...

To Analyze the Effect of CT and MRI in the Early Diagnosis of Residual and Recurrence of Hepatocellular Carcinoma After Interventional Treatment

Objective:To explore and analyze the effect of CT and MRI in the early diagnosis of residual cancer and recurrence after interventional treatment of liver cancer.Methods:The clinical data of 60 patients with primary liver cancer treated in our hospital from January 2020 to June 2021 were retrospectively analyzed,including 104 lesions.CT and MRI examinations were performed 2-6 months after transcatheter hepatic arterial chemoembolization(TACE).CT examination was the control group,and MRI examination was the observation group.Digital subtraction angiography(DSA)was used as the gold standard to compare the diagnostic results,sensitivity,specificity and accuracy of the diagnosis,tumor lesions and tumor envelope of the two groups.Results:The sensitivity,specificity and accuracy of the observation group were 95.24%(60/63),95.12%(39/41)and 95.19%(99/104),while the sensitivity,specificity and accuracy of the control group were 79.37%(50/63),73.17%(30/41)and 76.92%(80/104).The difference was statistically significant(P<0.05).In the observation group,40 cases(38.46%)of intrahepatic lesions were positive,20 cases(19.23%)of extrahepatic lesions were positive,the number of intrahepatic lesions(2.71±0.68)and the number of extrahepatic lesions(2.02±0.57)were all high.There were 35 cases(33.65%),15 cases(14.42%),(2.03±0.70)and(1.65±0.52)cases in the control group,and the difference was statistically significant(P<0.05);20.97%(13/62)of the observation group had obvious tumor capsule lesions,and 24.59%(15/61)of the control group had obvious tumor capsule lesions,and the difference was not statistically significant(P>0.05).Conclusion:MRI is more effective in the early diagnosis of residual tumor and recurrence after interventional treatment of hepatocellular carcinoma,with high sensitivity,specificity and accuracy,which can accurately display the lesions inside and outside the liver,observe whether there is tumor capsule,and provide reliable basis for clinical diagnosis and treatment.
