目的探讨电子计算机断层扫 描(Computed Tomography，CT)与核磁 共振(Magnetic Resonance Imaging， MRI)在原发性肝癌(primary hepatic carcinoma，PHC)介入术后病灶残留及复 发中的应用价值。方法 选取本院2015 年6月-2017年6月收治的PHC患者60例为 研究对象，共84个病灶，患者均在行经 导管肝动脉化疗栓塞术(transarterial chemoembolization，TACE)后2-6个 月来院复查，采用CT、MRI和数字减 影血管造影 ( D i g i t a l S u b t r a c t i o n Angiography,DSA)检查。以DSA为金标 准，比较CT和MRI检查对术后病灶残 留、复发诊断的准确度、敏感度、特异 度，以及对病灶肿瘤包膜的检出率。结 果 CT病灶残留或复发诊断准确度、敏 感度、特异度分别为79.76%、72.58%和 100.00%，MRI病灶残留或复发诊断准确 度、敏感度、特异度分别为94.05%、 91.94%和100.00%，MRI诊断的准确度和 敏感度显著高于CT(P<0.05)；CT肿瘤包 膜检出率为3.57%，显著低于MRI肿瘤包 膜检出率10.71%(P<0.05)。结论 MRI对于 PHC患者TACE术后疗效诊断准确度高，明 显优于CT诊断。

Objective To explore the application values of CT and MRI in the lesion residues and recurrence of primary hepatic carcinoma (PHC) intervention. Methods A total of 60 cases of PHC patients treated in our hospital from June 2015 to June 2017 were selected for the study with a total of 84 lesions, and all the patients were given the review at 2-6 months after the transarterial chemoembolization (TACE). The CT, MRI and digital subtraction angiography (DSA) were performed. The accuracy, sensitivity, specificity of the lesion residues and recurrence and the detection rate of the lesion tumor capsule were analyzed by CT and MRI examination taking the DSA as the gold standard. Results The accuracy, sensitivity and specificity of lesion residues and recurrence were 79.76%, 72.58% and 100.00% respectively by CT and were 94.05%, 91.94% 100.00% by MRI, and the accuracy and sensitivity of MRI diagnosis were significantly higher than those by CT (P<0.05). The detection rate of the lesion tumor capsule by CT was significantly lower than that by MRI (3.57% vs 10.71%) (P<0.05). Conclusion MRI has the high accuracy of efficacy diagnosis for PHC patients after TACE, which is significantly better than the CT diagnosis.
