【摘要】：目的分析细菌性肝脓肿患者超声造影特点,以期提高诊断符合率。方法选择2009年1月-2013年12月经超声造影检查的30例细菌性肝脓肿患者41个病灶资料,回顾性分析细菌性肝脓肿常规超声与超声造影表现,比较两种检查方法的诊断符合率。结果 30例细菌性肝脓肿患者中有21例单发、9例多发,累及部位肝右叶18例、肝左叶9例、肝左叶均累及3例,脓肿大小为直径2~9cm,平均(5.18±2.76)cm;超声造影检查:41个病灶均表现病灶缩小征,其中17个病灶呈花瓣样强化、14个病灶呈环状强化、10个病灶呈蜂窝状强化;24例患者28个病灶呈典型的陡直快进快出曲线;超声造影诊断符合率为93.33%,明显高于常规超声的73.33%,差异有统计学意义(χ2=9.24,P0.05)。结论超声造影检查集中了灰阶成像、彩色多普勒血流频谱和强化时间-强度曲线分析的优势,对提高细菌性肝脓肿超声诊断符合率有较高的应用价值。
[Abstract]:Objective to analyze the characteristics of contrast-enhanced ultrasonography in patients with bacterial liver abscess and to improve the diagnostic accuracy. Methods 41 lesions of 30 patients with bacterial liver abscess from January 2009 to 2013 were selected. The diagnostic accuracy of conventional ultrasound and contrast-enhanced ultrasonography for bacterial liver abscess was analyzed retrospectively. Results among the 30 patients with bacterial liver abscess, 9 had multiple lesions and 18 involved the right lobe of the liver. There were 9 cases of Zuo Ye and 3 cases of hepatic left lobe involvement. The size of abscess was 2 ~ 9 cm in diameter with an average of 5.18 卤2.76 cm. Among them, 17 lesions were petal-like enhancement, 14 lesions were annular enhancement, and 10 lesions were honeycombed enhancement. In 24 cases, 28 lesions showed a typical steepness fast in and out curve. The diagnostic coincidence rate of contrast-enhanced ultrasonography was 93.33, which was significantly higher than that of conventional ultrasound (73.33). The difference was statistically significant (蠂 ~ 2 / 9.24) P 0.05.Conclusion Ultrasonography focuses on the advantages of gray scale imaging, color Doppler blood flow spectrum and enhanced time-intensity curve analysis. It is valuable to improve the diagnostic accuracy of ultrasonic diagnosis of bacterial liver abscess.
