MRI在原发性肝癌早期诊断及TACE介入治疗术后疗效评价中的应用

Application of MRI in Early Diagnosis of Primary Liver Cancer and Curative Effect Evaluation after TACE Intervention Therapy

目的探讨磁共振成像(MRI)在原发性肝癌早期诊断及肝动脉化疗栓塞(TACE)介入治疗术后疗效评价中的应用效果。方法回顾性分析我院2017年1月至2019年6月期间收治的102例接受TACE介入治疗肝癌患者的临床病历资料以及MRI影像学资料。结果以数字减影血管造影(DSA)结果作为“金标准”,102例原发性肝癌患者共141个病灶,MRI诊断符合率100%;MR肝脏容积超快速三维成像(LAVA)序列对直径≤5cm的病灶肝癌包膜显示率.均高于T;加权像(T;WI)和T;加权像(T;WI)序列(P<005),T;WI序列对直径.≤5cm的病灶肝癌包膜显示率高于T;WI序列(P<005);MRI在原发性肝癌TACE介入治疗术后对残留.或复发病灶的检出率与DSA差异无统计学意义(P>005)。结论MRI在原发性肝癌早期诊断及TACE介入治疗术后疗效评价中的应用效果良好。

Objective To explore the application effect of magnetic resonance imaging(MRI) in the early diagnosis of primary liver cancer(PLC) and curative effect evaluation after transcatheter arterial chemoembolization(TACE) intervention therapy. Methods A retrospective analysis was performed on the clinical medical records and MRI imaging data of 102 liver cancer patients who underwent TACE intervention therapy and were admitted to the hospital from January 2017 to June 2019. Results Taking the results of digital subtraction angiography(Ds A) as the "golden standard", of the 102 PLC patients, there were 141 lesions. The diagnostic coincidence rate of MRI was 100%. The display rates of MR liver acquisition with volume aueleration(LAVA) sequence for liver cancer capsules with lesion diameter not longer than 5cm were higher than those of T;weighted image(T;WI) and T;weighted image(T;WI) sequences(P<0.05), and the display rates of T;WI were higher than those of T;WI(P<0.05). There were no significant differences between MRI and Ds A in the detection rates of residual or recurrent lesions after TACE intervention therapy(P>0.05). Conclusion The application effects of MRI are good in the early diagnosis of PLC and curative effect evaluation after TACE intervention therapy.
