摘　　要：目的:探讨肝动脉造影联合碘油CT对微小肝癌的诊断价值,提高微小肝癌的检出率。方法:对疑似肝癌复发患者30例行超声、MRI弥散加权成像(DWI)、肝动脉数字减影血管造影(DSA)联合碘油CT检查,以病理学诊断为金标准,评价不同诊断方法对微小肝癌的诊断价值。结果:组织病理学检查检出微小肝癌病灶72枚,超声病灶检出率为62.50%,DWI为68.06%,DSA联合碘油CT为97.22%,DSA联合碘油CT对病灶的检出率高于超声及DWI,差异有统计学意义(P<0.05);超声对微小肝癌诊断的敏感性、特异性分别为61.11%、50.00%,DWI为66.67%、50.00%,DSA联合碘油CT为97.22%、100.00%,DSA联合碘油CT诊断微小肝癌的敏感性及特异性最高。结论:与超声及DWI相比,肝动脉DSA联合碘油CT对微小肝癌的诊断敏感性最高,对提高微小肝癌检出率有重要意义。Objective:To investigate the value of Hepatic Arteriography(HAG)combined with Lipiodol CT(LIP CT)in the diagnosis of Micro Hepatocellular Carcinoma(MHCC).Methods:30recurrent patients with borderline MHCC had been diagnosed by means of ultrasonography,MRI(DWI)and DSA combined with LIP CT.With the pathological di- agnosis taken as the golden standard,different diagnosis methods had been evaluated.Results:Among those 30patients,72 MHCC were detected.All the 30patients were examined with ultrasonography,DWI and HAG combined with LIP CT,whose detection rates were respectively 62.50%,68.06%and 97.22%;there was statistical significance(P<0.05).The diagnostic sensitivity and specificity of ultrasonography for MHCC was 61.11%and 50.00%,respectively MRI(DWI)66.67%and 50.00%,HAG with LIP CT 97.22%and 100.00.Conclusion:HAG combined with LIP CT has the highest diagnostic sensitivity in comparison of ultrasonography and DWI,which plays a significant role in improving the detection rate in the diagnosis of MHCC.
