摘要
目的 :探讨肝脓肿双期增强CT异常灌注征象的诊断及应用价值。方法 :回顾分析了 13例细菌性肝脓肿双期CT扫描表现及病理检查特征。结果 :双期增强CT扫描病灶边缘动脉期出现“叶片状”及“楔形征”等异常灌注征象 ,门脉期该征象检出率明显低于动脉期 ;病灶周边异常灌注征象显著性多见于病灶发生早期 ,病灶内部往往呈“簇状征”、“多囊征”等不典型CT征象改变。结论 :肝脓肿周边异常灌注征象对其诊断及鉴别诊断均有参考价值。
Objective:To discuss the diagnostic value of the marginal abnormal, perfusion sign of the bacterial liver abscess by double-phase enhanced CT. Methods:Review and analyse 13 cases of bacterial liver abscess by spiral-CT double-phase scan mode and the character of pathology. Results:In the artery-period the perfusion sign showed“leaf blade ” sign or “cuniform strengthen” sign on the focus marginal,but in the portal-venous-period its appearance is lower than the artery-period; the abnormal sign most appear in the artery-period early;and in the focus most shows “many theca” sign;Conclusion:The marginal abnormal perfusion sign of bacterial liver abscess has the important diagnostic value to the bacterial liver abscess.
