目的分析超声造影(CEUS)和增强CT(CECT)在诊断小肝细胞癌(sHCC)增强模式及诊断结果的一致性。方法回顾性分析sHCC患者39例(43处病灶)CEUS和CECT造影增强模式及诊断结果,进行一致性分析。结果 39例CEUS和CECT一致性出现动脉期强化、门脉期及延迟期廓清、诊断结果分别为56%,63%、42%,Kappa值分别为0.44、0.43、0.40,一致性程度为中等水平。结论 CEUS和CECT出现一致性特征诊断sHCC时,可能会降低sHCC的诊断敏感性,两者的互补应用以及结合血清学、病理学方法有助于提高sHCC的诊断率。 Objective To analyze the consistency of CEUS and CECT in the diagnosis of small hepatocellular carcinoma (sHCC) and the diagnostic results. Methods The CEUS and CECT contrast enhancement patterns and diagnostic results of 39 cases (43 lesions) of sHCC patients were analyzed retrospectively. Results The consistency of CEUS and CECT in 39 cases showed arterial phase enhancement, clear portal phase and delayed phase, the diagnostic results were 56%, 63%, 42%, Kappa values ​​were 0.44,0.43,0.40 respectively, and the consistency was moderate . Conclusions The consistent diagnosis of sHCC by CEUS and CECT may reduce the diagnostic sensitivity of sHCC. Complementary application of both CEUS and CECT combined with serological and pathological methods may improve the diagnostic rate of sHCC.
