【摘要】：目的探讨超声造影用于诊断肝脓肿的影像学表现及临床价值,为肝脓肿的诊断方法选择提供参考。方法收集2010年1月-2016年6月医院确诊的100例肝脓肿患者临床资料,分析术前常规二维超声及超声造影检查结果。结果常规二维超声术前诊断为肝脓肿者89例,诊断准确率89.00%,其中脓肿炎性期、脓肿形成初期、脓肿形成期的诊断准确率分别为72.22%、88.57%、95.74%,不同分期患者诊断准确率比较,差异有统计学意义(P0.05);超声造影术前诊断为肝脓肿者97例,诊断准确率97.00%,诊断准确率高于常规二维超声(P0.05),其中脓肿炎性期、脓肿形成初期、脓肿形成期的诊断准确率分别为88.89%、97.14%、100.00%,不同分期患者诊断准确率比较差异有统计学意义(P0.05);超声造影检查时脓肿炎性期、脓肿形成初期影像学表现主要表现为病灶动脉期的高增强,静脉期、延迟期低增强,显示范围较常规超声增大,脓肿形成期影像学表现为病灶动脉期高增强,静脉期、延迟期低增强现象减少,显示范围较常规超声增大。结论超声造影用于诊断肝脓肿能明显提高诊断准确性,影像学上肝脓肿不同时期超声造影表现各有特点。
[Abstract]:Objective to investigate the imaging features and clinical value of contrast-enhanced ultrasonography in the diagnosis of liver abscess. Methods the clinical data of 100 cases of liver abscess diagnosed from January 2010 to June 2016 were collected. Results 89 cases of liver abscess were diagnosed by conventional two-dimensional ultrasonography before operation. The diagnostic accuracy was 89.00%. The abscess was in inflammatory stage and early stage of abscess formation. The diagnostic accuracy of abscess was 72.22 and 88.57 and 95.74, respectively. The diagnostic accuracy of different stages of abscess was significantly higher than that of P0.05. 97 cases were diagnosed as liver abscess before sonography, the diagnostic accuracy was 97.00, and the diagnostic accuracy was higher than that of conventional two-dimensional ultrasound (P0.05), especially in the inflammatory stage of abscess and the early stage of abscess formation. The diagnostic accuracy of abscess in different stages was 88.89 and 97.140.The diagnostic accuracy of patients with different stages was significantly different (P 0.05). In the inflammatory stage of abscess, the imaging manifestations of the early stage of abscess were high enhancement in arterial phase, low enhancement in venous phase and delayed phase, and the display range was larger than that in conventional ultrasound. The imaging manifestations of abscess were high enhancement in arterial phase, low enhancement in venous phase and delayed phase. Conclusion contrast-enhanced ultrasonography can improve the diagnostic accuracy of liver abscess.

【正文快照】： 肝脓肿属于良性病变,主要是由细菌及阿米巴原虫、真菌等感染所致[1-3],与肝脏恶性肿瘤本质完全不同,肝脓肿的准确诊断对于治疗方案的选择具有重要意义。目前对肝脓肿的辅助诊断主要依据肝脏超声检查,相对诊断准确性较好,但是由于临床抗菌药物的应用等导致肝脓肿的超声影像学表
