原发性肝癌TACE术后MRI和DSA随访对比分析

【目的】对比分析MRI和DSA在原发性肝癌经导管肝动脉化疗栓塞（transcatheter arterial chemoembolization,TACE）治疗后肿瘤残存的诊断价值。【方法】临床确诊的24例原发性肝癌患者,分别于肝癌TACE治疗后1~3个月行MRI及DSA,2项检查间隔时间为1~5 d。分析和比较MRI和DSA对肿瘤残存和新发的显示情况。【结果】本组24例共68个原发肿瘤灶经TACE治疗后,MRI共检出14例28个残存灶,10例30个新发病灶,DSA检出14例30个残存灶,11例32个新发病灶;MRI对残存灶的敏感性、特异性和准确率分别为93%、100%和97%。【结论】MRI为原发性肝癌TACE术后评估和随访较为理想的检查方法。

A comparison study of MRI and DSA in the follow-up of HCC treated with TACE

【Objective】To study the value of MRI and DSA examinations Compared with DSA in the follow up of HCC treated with transcatheter hepatic arterial chemoembolization（TACE）.【Methods】24 patients with HCC were treated with TACE.All the patients performed MRI and DSA within 1-3 months after of TACE.The interval between two examinations was 1-5 days.MRI results were compared with DSA to display the HCC.【Results】MRI found 28 residual viable tumor lesions in 14 patients and 30 new lesions in 10 patients.DSA showed 30 residual viable tumor lesions in 14 patients and 32 new lesions in 11 patients.For the residual viable tumor,the sensitivity and specificity of MRI were 93% and 100%,the accuracy was 97%.【Conclusion】Both DSA and MRI can be used as valuable choice in follow up of HCC after TACE.
