中文摘要：

目的研究超声造影在腹部实质脏器损伤诊断中的价值。方法对86例腹部实质脏器损伤患者的常规彩超检查和超声造影资料进行分析，比较常规彩超与超声造影在诊断腹部实质脏器损伤的敏感性、特异性、准确性差异。结果超声造影诊断腹部实质损伤的敏感性、特异性、准确性分别为97．5％、83．3％、96．5％，常规彩超诊断腹部实质损伤的敏感性、特异性、准确性分别为70．0％、50．0％、68．6％，2种方法的敏感性、特异性、准确性比较差异有统计性意义（P〈0．01）。结论超声造影在诊断腹部实质脏器损伤方面明显优于常规彩超，它具有操作相对简单、实时、无需做过敏试验、诊断的敏感性、特异性、准确性高等优点，能发现常规彩超不能发现的小的裂伤、挫伤、活动性出血，腹部外伤后要尽可能做超声造影检查。

英文摘要：

Objective To study on the value of contrast-enhanced ultrasonography（CEUS） in the diagnosis of abdominal parenchymatous organ injury. Methods The conventional uhrasonography and contrast-enhanced ultrasonography findings were comparatively analyzed in 86 cases with abdominal parenchymatous organ injury. The sensitivity, specificity, aecuracy were compared between the two methods. Results The sensitivity, specificity, accuracy of contrast-enhanced uhrasonography was 97.5% , 83.8% and 96.5 % , respectively;while the conventional ultrasonography was 70% , 50% and 68.6%, respectively. The difference had significant difference between the two methods. Conclusion Contrast-enhanced ultrasonography is superior to conventional uhrasonography in the diagnosis of abdominal parenchymatous organ injury. This method had advantage of simplicity, real-time, no need allergy test, high sensitivity, specificity and accuracy. It can find small laceration, contusions and active bleeding that the conventional ultrasonography cannot do. The contrast-enhanced uhrasonography is the first choice for the patients with abdominal trauma.
