摘　　要：目的探讨MRI与CT对原发性肝癌肝动脉化疗栓塞(Transcatheter arterial chemoembolization,TACE)术后疗效的评估价值。方法收集我院2015年9月-2016年12月经TACE治疗的128例原发性肝癌患者资料,均行MRI、CT及数字减影血管造影(DSA)检查,以DSA结果为金标准,并对MRI、CT的诊断结果进行对比分析。结果 128例患者中,DSA显示病灶166个,其中115个病灶存在肿瘤复发或残余,51个病灶无肿瘤复发或残余;MRI检出108个复发或肿瘤残余病灶,准确率为94.53%,敏感性为93.04%,特异度为100.00%;CT检出76个复发或肿瘤残余病灶,准确率为69.53%,敏感性为66.08%,特异度为100.00%;MRI诊断的准确性高于CT,差异具有统计学意义(P<0.05);MRI对有包膜病灶的检出率较CT高,差异具有统计学意义(P<0.05)。结论 MRI对原发性肝癌TACE术后复发及残余病灶诊断的准确性高于CT,对原发性肝癌TACE术后的疗效评估具有较高价值。Objective To study the value of MRI and CT in the diagnosis of lesions after TACE for primary liver cancer （PHC）. Methods The clinical data of 128 patients received TACE for the treatment of primary hepatocellular carcinoma in our hospital between September 2015 and December 2016 were analyzed. MRI, CT and DSA were given to all these patients, with digital subtraction angiography （DSA） as the gold standard. The diagnostic results of MRI and CT were compared. Results As the DSA findings shown, there were 166 lesions found in the 128 patients. 115 lesions were found to be recurrent or residual tumor and 51 recurrent or residual tumor lesions. There were 108 recurrent or re sidual tumor lesions detected through MRI. The accuracy, sensitivity and specificity were 94.53%, 93. 04%and 100.00%. There were 76 recurrent or residual tumor lesions found by CT. The accuracy, sensitivity and specificity were 69.53% ,66.08% and 100.00%. The diagnostic accuracy of MRI was high compared with that of CT （P〈0.05）. The detection rate of MRI for the determination of lesions with tumor capsule after resection of the lesions was higher than that of CT （P〈0.05）. Conclusion The sensitivity, accuracy and the detection rate of tumor capsule lesions of MRI are all higher than those of CT, which is of high value for the diagnosis of recurrent or resiual lesions after TACE for primary hepatocellular carcinoma.
