摘　　要：目的分析肝细胞癌(HCC)Sonazoid超声造影(CEUS)的特点与病理分化程度的相关性。方法纳入行CEUS检查并经病理确诊为HCC的患者64例,共64个病灶,根据病理分化程度将其分为高、中、低分化组,分别为6、48和10例。比较不同病理分化程度HCC的CEUS动脉期增强形态、增强水平和增强模式。结果动脉期增强形态分为均匀增强和不均匀增强2种,低分化组所有病灶及58.3%中分化组病灶呈不均匀高增强;高分化组病灶可呈均匀高增强、均匀等增强和不均匀高增强3种表现。动脉期,所有中、低分组病灶和66.7%高分化组病灶呈高增强,不同分化程度HCC的增强水平差异有统计学意义(P<0.01);门脉期,高、中、低分化组分别有16.7%、25.0%和70.0%的病灶消退成低增强,不同分化程度HCC的增强水平差异有统计学意义(P<0.05);延迟期,75%中分化组病灶和所有低分化组病灶呈低增强,66.7%高分化组病灶呈等增强,不同分化程度HCC的增强水平差异有统计学意义(P<0.01);Kupffer期,所有低分化组和95.8%中分化组病灶呈低增强,高分化组中仍有50%的病灶呈等增强,不同分化程度HCC的增强水平差异有统计学意义(P<0.01)。高分化组病灶表现为多种CEUS模式,中分化组病灶以“快进快退”、“快进慢退”为主,90.0%低分化组病灶呈“快进快退”模式,不同分化程度HCC的CEUS模式差异有统计学意义(P<0.01)。结论Sonazoid-CEUS在评估HCC病理分化程度方面具有一定价值。Objective To analyze the correlation between the characteristics of Sonazoid contrast-enhanced ultrasound(CEUS)and pathological differentiation in hepatocellular carcinoma(HCC).Methods A total of 64 patients with HCC diagnosed pathologically by CEUS examination were included,and a total of 64 lesions were divided into the high,medium and low differentiation groups(6,48 and 10 cases,respectively)according to the degree of pathological differentiation.The enhancement pattern,enhancement level and enhancement pattern of CEUS arterial stage in HCC with different pathological differentiation were compared.Results The enhancement pattern of arterial phase was divided into the uniform enhancement and the uneven enhancement.All lesions in the low differentiated group and 58.3%in the middle differentiated group showed uneven and high enhancement.In the highly differentiated group,lesions showed homogenous hyperintensification,homogenous isointensification and non-homogenous hyperintensification.At arterial stage,all lesions in the middle and low differentiated groups and 66.7%lesions in the highly differentiated group showed high enhancement,and the enhancement levels of HCC with different differentiation degrees were significantly different(P<0.01).At the portal stage,16.7%,25.0%and 70.0%lesions in the high,medium and low differentiated HCC groups subsided to low enhancement,and the enhancement levels of HCC with different differentiation degrees were significantly different(P<0.05).In the delayed stage,75%lesions in the medium-differentiated group and all lesions in the low-differentiated group showed low enhancement,and 66.7%lesions in the highly differentiated group showed equal enhancement.Enhancement levels of HCC with different differentiation degrees were significantly different(P<0.01).At the Kupffer stage,all lesions in the low differentiated group and 95.8%of the moderately differentiated group showed low enhancement,while 50%lesions in the highly differentiated group still showed equal enhancement,and there we
