3.0T MRI与64排CT评价原发性肝癌介入治疗后疗效的价值

Value of 3.0T MRI and 64-slice CT in Evaluating the Efficacy After Interventional Therapy of Primary Liver Cancer

目的探讨磁共振成像(MRI)与电子计算机断层扫描(CT)评价原发性肝癌介入治疗后疗效的价值。方法回顾性分析2015年3月-2017年1月间收治的48例原发性肝癌(PLC)患者临床资料,患者均经导管肝动脉化疗栓塞术(TACE)治疗。患者术后复查时均经3.0TMRI、64排CT及数字减影血管造影(DSA)检查,以DSA为标准,比较MRI和CT检查发现残留病灶、复发病灶和病灶包膜的价值。结果 (1)MRI检查残留、复发病灶灵敏度、准确率均高于CT检查(P<0.05);(2)MRI检出Ⅱ型碘油沉积残留、复发病灶率高于CT(P<0.05);Ⅰ型、Ⅲ型、Ⅳ型对比,差异无统计学意义(P>0.05);(3)MRI病灶包膜检出率高于CT(P<0.05)。结论 3.0TMRI更有利于检出原发性肝癌经TACE后残留、复发病灶,受碘油影响较CT小,MRI检出包膜能力也高于CT,在评估PLC经TACE治疗后疗效价值更高。

Objective To explore the value of magnetic resonance imaging(MRI)and computed tomography(CT)in the evaluation of efficacy after interventional therapy of primary liver cancer.Methods The clinical data of 48 patients with primary liver cancer(PLC)admitted to our hospital during March 2015 to January 2017 were analyzed retrospectively.All patients were given transcatheter arterial chemoembolization(TACE),and they were given 3.0 TMRI,64-slice CT and digital subtraction angiography(DSA)examination postoperative review.DSA was used as the standard to compare the value of residual lesions,recurrent lesions and lesion capsule by MRI and CT.Results The sensitivity and accuracy of residual and recurrent lesions by MRI examination were higher than those by CT examination(P<0.05).The detection rates of residual and recurrent lesions of type II lipiodol deposition by MRI were higher than those by CT(P<0.05).There was no significant difference in type I,type III and type IV(P >0.05).The detection rate of capsule by MRI was higher than that by CT(P<0.05).Conclusion 3.0T MRI is more conducive to the detection of residual and recurrent lesions after TACE in PLC,and the effect of iodized oil to the lesion is smaller than that of CT.MRI also has higher ability of capsule detection rate than CT,and it has higher value in evaluating the efficacy after TACE in PLC.
