目的 比较CT及MRI对原发性肝癌经导管肝动脉化疗栓塞(TACE)术后疗效评估的价值.方法 以45例原发性肝癌患者为研究对象,入选患者均采用TACE治疗3～5次,治疗后行CT、MRI病灶检查及数字减影血管造影检查,以数字减影血管造影检查作为比较标准,分析CT及MRI检查的病灶残余或病灶复发结果及肿瘤病灶包膜检出情况.结果 TACE术后病灶残余或病灶复发的扫描准确率和扫描敏感性方面,CT扫描显著低于MRI扫描,差异具有统计学意义(P<0.05);TACE术后肿瘤包膜检出率方面,CT扫描显著低于MRI扫描,差异具有统计学意义(P<0.05);TACE术后不同类型碘油沉积病灶残余或病灶复发的检出率方面,CT扫描显著低于MRI扫描,差异具有统计学意义(P<0.05).结论 与CT检查方式比较,MRI检测在TACE术后病灶残余或病灶复发有着较高的的准确率和敏感性,不仅可有效显示肿瘤包膜情况,也检测出不同类型碘油沉积的病灶残余或病灶复发,MRI对原发性肝癌TACE术后的疗效评估优于CT对原发性肝癌TACE术后的疗效评估.%Objective To compare the value of computed tomography(CT)and magnetic resonance im-aging(MRI)in assessing the curative effect of primary liver cancer after transcatheter arterial chemoembolization (TACE). Methods 45 patients with primary hepatocellular carcinoma treated with TACE for 3 ～ 5 times were included in the research. CT ,MRI and digital subtraction angiography (DSA) were performed after treatment. DSA was used as a standard to analyze the lesions ,residual or lesion recurrence and the detection of tumor cap-sule in CT and MRI DSA. Results The scanning accuracy and sensitivity of residual lesions or lesion recurrence after TACE in CT was much lower than MRI ,and there is a significant difference between the two groups (P <0.05). In terms of tumor capsule detection accuracy after TACE ,CT was much lower than MRI(P < 0.05). In detection rate of residual or lesion recurrence in different types of lipiodol deposition after TACE ,CT was much lower than MRI (P < 0.05). Conclusions Compared with the CT test ,MRI detection has a higher accuracy and sensitivity of residual lesions or recurrence after TACE. MRI can not only effectively show the tumor cap-sule ,but also detect residual lesion or lesion recurrence of different types of lipiodol deposition. MRI is superior to CT in the evaluating the curative effect of primary liver cancer after TACE.
