摘　　要：目的研究原发性肝癌(PHC)介入治疗后病灶残留中MSCT、MRI多模态成像的诊断价值。方法选取2017年1月-2021年4月期间本院接治的120例原发性肝癌患者展开研究,术前DSA造影检出150个病灶,术后3个月对患者进行随访检测,对比MSCT、MRI多模态成像对PHC介入治疗后病灶残留的诊断效能。结果(1)碘油沉积良好病灶45个,DWI呈均匀低信号表现,部分缺损病灶为105个,DWI病灶为均匀低信号表现,缺损区域呈高信号表现;(2)MRI多模态成像的肿瘤包膜检出率明显高于MSCT(P<0.05);(3)在术后3个月DSA共检出病灶残留110个,无病灶残留45个,MRI多模态成像检测的准确度、敏感度、特异度、AUC值均明显大于MSCT(P<0.05);(4)术前瘤区的ADC值明显低于肿瘤坏死区与碘油沉积区,且碘油沉积区明显低于肿瘤坏死区(P<0.05)。结论应用MRI多模态成像能清晰显示患者的病灶残留情况,在PHC介入治疗后病灶残留评估中的诊断价值高于多层螺旋CT,具有一定临床推广应用价值。Objective To study the diagnostic value of MSCT and MRI multimodal imaging in residual lesions after interventional treatment of primary liver cancer(PHC).Methods From January 2017 to April 2021,120 patients with primary liver cancer treated in our hospital were selected for the study.150 lesions were detected by DSA imaging before surgery,and the patients were followed up for 3 months after surgery,compared with MSCT,The diagnostic efficacy of MRI multimodal imaging for residual lesions after PHC interventional therapy.Results(1)There were 45 lesions with good iodi nated oil deposition,showing uniform low signal on DWI,and 105 lesions with partial defect,show ed uniform low signal on DWI lesions,and high signal on the defect area;(2)The tumor envelope detection rate of MRI multimodal imaging was significantly higher than that of MSCT(P<0.05);(3)At 3 months after surgery,110 lesions were detected by DSA and 45 lesions were not detected.The a ccuracy,sensitivity,specificity and AUC of MRI multimodal imaging detection were significantly highe r than that of MSCT(P<0.05);(4)The ADC value in the tumor area before surgery was significantly low er than that in the tumor necrosis area and the lipiodol deposit area,and the lipiodol deposit area wa s significantly lower than that in the tumor necrosis area(P<0.05).Conclusion The application of MRI multimodal imaging can clearly show the residual situation of the patients,and the diagnostic value o f the residual assessment of the lesions after PHC interventional therapy is higher than that of multislice spiral CT,which has certain clinical application value.
