摘要
目的探讨肝脓肿的超声造影特点及其诊断价值。方法经CT及其临床诊断的肝脓肿患者11例,12个病灶,均经常规超声及超声造影检查,记录超声造影开始时间、达峰时间等。结果 11个病灶超声造影动脉期均能清晰显示快速增强,4个病灶呈蜂窝状强化,7个病灶呈厚壁环状强化;1个病灶虽呈蜂窝状改变但分隔处为等增强。12个病灶内部均可见多发或单发的片状无增强区域,即液化坏死区。结论超声造影能反映肝脓肿的病变特征,提高了对肝脓肿的诊断。
Objective To investigate the characteristics of contrast-enhanced ultasonography of liver abscess. Methods Twelve liver abscesses in 11 patients confirmed by CT and clinical manifestation were examined using conventional ultrasound and contrast-enhanced ultrasound,and the beginning time and the peak time were recorded. Results The contrast-enhanced ultrasound showed enhancement in the artery phase in 11 abscesses（91.7%） ,including 4 abscesses（33.3%） for honeycomb-like enhancement with some small unenhanced cavities inside and 7 abscesses（58.3%） for peripheral wall thickening enhancement and internal sponge-like enhancement,and a honeycomb change but internal septal isoenhancemen in one（8.3%） .Multiple or single sheets of non-enhanced region were found in all abscesses. Conclusion Contrast-enhanced ultrasound features are variable,which is helpful in the diagnosis of the liver abscess.
