摘要

目的：

探讨10 mm肝细胞肝癌（hepatocellular carcinoma，HCC）超声造影的特征。

方法：

回顾性分析手术病理学检查证实的34例10 mm HCC病灶的超声造影图像特征，总结超声造影时相变化。

结果：

34例共34个病灶中，100%（34个）表现为动脉期高回声增强，61.8%（21个）表现为门静脉期低回声增强，38.2%（13个）表现为门静脉期等回声增强，其中延迟期减退7例，延迟期仍呈等回声6例。在10 mm HCC的超声造影中，开始增强时间、达峰时间、呈等回声及低回声时间分别是（18.563.94）、（23.884.59）、（32.336.54）及（134.2166.38）s。若以动脉期高回声增强，门静脉期及延迟期低回声增强作为诊断指标，超声造影诊断10 mm HCC的准确率为61.8%。若以动脉期出现高回声增强，门静脉期呈等或低回声增强，延迟期呈低回声增强为诊断指标，其准确率为82.4%；若再结合既往肿瘤病史，其诊断准确率可达91.1%。

结论：

超声造影时相分析有助于提高10 mm HCC的诊断准确率。

Abstract

Objective:

To evaluate the value of contrast-enhanced ultrasound (CEUS) in the diagnosis of 10 mm hepatocellular carcinoma (HCC).

Methods:

Thirty-four cases with pathologically proven 10 mm HCC were enrolled in this study and the image features on CEUS were analyzed retrospectively.

Results:

All cases were hyper-enhanced in arterial phase. 61.8% (21/34) were hypoenhanced and 38.2% (13/34) were iso-enhanced in portal venous phase. In those cases with iso-enhancement in portal vein phase

7 cases showed hypo-enha

ncement and 6 cases showed iso-enhancement in delayed phase. The average enhancement initial time

the time to peak

the time to isoechogenity

and the time to hypoechogenicity were (18.563.94)

(23.884.59)

(32.336.54)

and (134.2166.38) s

respectively. The diagnostic accuracy was 61.8% if the diagnostic standard for 10 mm HCC was set as hyperenhancement in arterial phase and hypo-enhancement in portal venous and delayed phases; However

the diagnostic accuracy was improved to 82.4% if the standard was hypo-enhancement in arterial phase and hypo-enhancmeent or iso-enhancement in portal venous phase and hypo-enhancement in delayed phase. Furthermore

the diagnostic accuracy was improved to 91.1% when combining HCC history.

Conclusion:

Analysis of contrast phase for 10 mm HCC might be helpful in improving the diagnostic accuracy.
