目的探讨超声造影对原发性小肝癌和局灶性结节增生的鉴别诊断价值。方法抽取进行超声造影检查并经病理确诊的7例FNH和11例HCC患者,比较两者造影剂增强的到达时间(AT)、达峰时间(TTP)、增强水平、增强形态、增强随时相的变化。结果 FNH与HCC的AT和TTP无明显差异,两者造影动脉期多数呈高增强,但FNH门脉期及延迟期多数仍呈高增强或等增强,HCC门脉期及延迟期多数呈低增强或无增强。结论小肝癌与肝局灶性结节增生在超声造影的表现上有显著差异,具有很好的鉴别诊断价值。
Objective To investigate the differential diagnosis of primary small hepatocellular carcinoma and focal nodular hyperplasia by contrast-enhanced ultrasound. Methods Totally 7 patients with FNH and 11 patients with HCC diagnosed by contrast-enhanced ultrasonography were enrolled in this study. The contrast-enhanced time of arrival (AT), peak time (TTP), enhanced level, enhanced morphology and enhanced phase contrast Variety. Results There was no significant difference between AT and TTP in FNH and HCC. Most of the arterial phase of FNH and HCC showed high enhancement. However, most of portal venous phase and delayed phase of FNH still showed high enhancement or equal enhancement. Most of portal phase and delayed phase of HCC showed low enhancement Or no enhancement. Conclusion Small hepatocellular carcinoma and focal hepatic nodular hyperplasia have significant differences in the performance of ultrasound contrast, which has a good differential diagnostic value.
