CT与MRI评价原发性肝细胞癌介入治疗后病灶残留的临床价值

Clinical value of CT and MRI in evaluating the residual lesions of primary hepatocellular carcinoma after interventional therapy

目的探究CT与MRI评价原发性肝细胞癌介入治疗后病灶残留的临床价值。方法回顾性分析2018年8月至2020年8月赣州市第五人民医院收治的82例原发性肝细胞癌患者的临床资料。所有患者均在介入治疗后进行CT动态增强与MRI检查,并将数字减影血管造影(DSA)检查结果作为金标准,比较两种检查方法对病灶残留的灵敏度、特异度、准确性及诊断效能。结果MRI检查诊断病灶残留的敏感度、特异度、准确率及Kappa值分别为89.71%、100.00%、92.86%、0.929,高于CT动态增强的69.12%、100.00%、78.57%、0.578,差异有统计学意义(P<0.05)。结论对于临床诊断原发性肝细胞癌介入治疗后病灶残留,MRT比CT动态增强有更准确的结果,能更早检查出复发的病灶,对后续治疗方案的制定有重大意义。

Objective To explore the clinical value of CT and MRI in evaluating the residual lesions of primary hepatocellular carcinoma after interventional therapy.Methods The clinical data of 82 patients with primary hepatocellular carcinoma admitted to the Fifth People′s Hospital of Ganzhou City from August 2018 to August 2020 were retrospectively analyzed.The results of digital subtraction angiography(DSA)were taken as the gold standard.The sensitivity,specificity,accuracy and diagnostic efficiency of the two methods were compared.Results The sensitivity,specificity,accuracy and Kappa value of MRI in the diagnosis of residual lesions were 89.71%,100.00%,92.86%and 0.929 respectively,which were higher than 69.12%,100.00%,78.57%and 0.578 of dynamic contrast-enhanced CT,and the differences were statistically significant(P<0.05).Conclusion For the clinical diagnosis of residual lesions of primary hepatocellular carcinoma after interventional therapy,MRI has a more accurate result than CT dynamic enhancement,and it can examine the recurrent lesions earlier,and is of great significance to the formulation of subsequent treatment plans.
