摘　　要：目的探讨计算机体层摄影(CT)与核磁共振(MRI)诊断原发性肝癌介入治疗后病灶残留与复发的应用价值。方法选取2018年1月至2020年12月濮阳市油田总医院收治的75例原发性肝癌并接受经导管肝动脉化疗栓塞术(TACE)介入治疗的患者作为研究对象,术后6个月来院复查并行CT、MRI和数字减影血管造影(DSA)。分别计算单独增强CT、单独增强MRI和增强CT联合MRI诊断术后病灶残留和复发的应用价值,检测指标包括灵敏度、特异度、阳性预测值和阴性预测值。结果以DSA诊断术后病灶残留和复发作为“金标准”,确诊49例为病灶残留和复发的阳性病例,占65.33%,26例为病灶完全灭活的阴性病例,占34.67%。增强CT联合MRI诊断方案的灵敏度高于增强CT诊断方案和增强MRI诊断方案(P<0.05),增强CT联合MRI诊断方案的特异度与增强CT诊断方案和增强MRI诊断方案比较,差异无统计学意义(P>0.05),增强CT联合MRI诊断方案的阳性预测率与增强CT诊断方案和增强MRI诊断方案比较,差异无统计学意义(P>0.05),增强CT联合MRI诊断方案的阴性预测率高于增强CT诊断方案和增强MRI诊断方案(P<0.05)。结论单独CT和单独MRI对于原发性肝癌介入治疗后病灶残留与复发均有一定的诊断价值,联合应用二者诊出率更高,有助于临床诊断和复发治疗。Objective To explore the application value of computed tomography(CT)and magnetic resonance imaging(MRI)in diagnosing the residual and recurrence of primary liver cancer after interventional therapy.Methods A total of 75 patients with primary liver cancer who were treated with transarterial chemoembolization(TACE)interventional treatment were selected in Puyang Oilfield General Hospital from January 2018 to December 2020.The patients came to the hospital for reexamination with CT,MRI and ultrasound 6 months after digital subtraction angiography(DSA).The application value of enhanced CT alone,enhanced MRI alone,and enhanced CT combined with MRI in diagnosing residual and recurrence after surgery were calculated.The detection indicators included sensitivity,specificity,positive predictive value and negative predictive value.Results Taking DSA as the gold standard for diagnosing residual and recurring lesions,49 cases were diagnosed as positive cases with residual lesions and recurrence,accounting for 65.33%,and 26 cases were negative cases with completely inactivated lesions,accounting for 34.67%.The sensitivity of the enhanced CT combined with MRI diagnosis plan is higher than that of the enhanced CT diagnosis plan and the enhanced MRI diagnosis plan(P<0.05).There was no difference in the specificity among the enhanced CT combined with MRI diagnosis plan,the enhanced CT diagnosis plan and the enhanced MRI diagnosis plan(P>0.05).The positive prediction rate of the enhanced CT combined with MRI diagnosis plan was similar to that of the enhanced CT and enhanced MRI diagnosis plan(P>0.05).The negative prediction rate of the enhanced CT combined with MRI diagnostic program was higher than that of the enhanced CT diagnostic program and the enhanced MRI diagnostic program(P<0.05).Conclusion Both CT and MRI alone have a certain diagnostic value for the residual and recurrence of primary liver cancer after interventional therapy.The combined application of the two has a higher diagnosis rate,which is helpful for clinical d
