摘要
目的:探讨超声造影在肝局灶性结节增生(FNH)的应用及诊断价值。方法:回顾分析2009年1月至2011年12月来本院本科就诊的16例患者的肝局灶性结节增生的彩色多普勒声像图及超声造影特征。结果:肝局灶性结节增生的二维超声表现为稍低或等回声结节,彩色多普勒血流显像于部分结节内可见"轮辐"状动脉血流;超声造影动脉期全部病灶迅速强化(9～15 s),显示为均匀高增强,大部分病灶可见"轮辐"状离心性增强,部分病灶还可见中央瘢痕低增强。结论:超声造影能动态显示FNH的血流灌注特征,在FNH的诊断和鉴别诊断中有重要价值。
Objective： To investigate the application and diagnostic value of contrast-enhanced uhrasonography for hepatic focal nodular hyperplasia （FNH）. Methods： We retrospectively reviewed the characteristics of uhrasonography and contrast-enhanced ultrasonography of 16 patients with FNH who were admitted to department of uhrasanography, Guangzhou Panyu Central Hospital, between January 2009 and December 2011. Results： FNH appeared isoechoic or hypoechoie as assessed by two-dimensional uhrasonography, and might be featured by the presence of spoke-like arterial blood flow in a number of nodules, a result suggested by color Doppler uhrasonography. During contrast-enhanced uhrasonograpby, an evenly distributed intensified loci, particularly spoke-like radiating intensified foci noted in most foei, could be revealed at arterial phase （9 - 15 seconds）. Whilst a minority of foci may be identified owing to the presence of central scar-like intensification. Conclusion： Ultrasonography dynamically demonstrates the characteristics of blood peffusion and may play a crucial role in the diagnosis and differential diagnosis of FNH.
