常规超声与超声造影及增强CT对弥漫性肝癌的诊断价值比较

The role of contrast-enhanced ultrasound in the diagnosis of diffuse hepatocellular carcinoma

目的比较常规超声、超声造影及增强CT对弥漫性肝癌的诊断价值。方法回顾性分析42例弥漫性肝癌患者的常规超声、超声造影和增强CT表现,并对三种检查诊断结果进行对比。结果常规超声对弥漫性肝癌的诊断准确率为38.1%(16/42),超声造影对弥漫性肝癌的诊断准确率为81.0%(34/42),增强CT对弥漫性肝癌的诊断准确率为83.3%(35/42)。超声造影与增强CT对弥漫性肝癌的诊断准确率明显高于常规超声(P<0.05);超声造影和增强CT诊断的准确率比较,差异没有统计学意义(P>0.05)。结论与常规超声检查结果相比,超声造影提高了弥漫性肝癌的诊断准确率,且与增强CT诊断准确率相近。

Objective To compare the diagnostic value of conventional ultrasonography, contrast-enhanced ultrasonogra- phy （CEUS） and contrast-enhanced CT in diffuse-type hepatocellular carcinoma （D-HCC）. Methods 42 D-HCC patients were treated with conventional ultrasound, ultrasonic imaging and enhanced CT performance. Results The accuracy identify D-HCC of conventional ultrasonography, CEUS and contrast-enhanced CT were was 38% （16/42）, 81% （34/42） and 83 % （35/42）. The accurate diagnosis rates in the CEUS and contrast-enhance CT were significantly higher than that in the conventional ultrasonog- raphy （P〈0. 05）. There was no difference between CEUS and contrast--enhance CT. Conclusions Compared with conventional ultrasonography,CEUS can increase the diagnostic accuracy in the D-HCC. That is similar to contrast-enhance CT.
