摘　　要：目的探讨超声造影增强模式在低位胆道梗阻病灶良恶性鉴别诊断中的应用价值。方法回顾性分析我院53例经病理诊断的低位胆道梗阻患者的超声造影诊断结果及其增强模式,计算超声造影诊断低位胆道梗阻恶性病灶的准确率、特异性、敏感性、阳性预测值及阴性预测值,总结良恶性超声造影特点。结果超声造影诊断恶性病灶的准确率、敏感性、特异性、阳性预测值及阴性预测值分别为94.3%、92.3%、96.3%、96.0%及92.9%。恶性病灶超声造影增强模式多表现为动脉相非均匀高增强(21例)或等增强(3例),并在静脉相有明显消退;良性病灶多表现为动脉相等增强(21例),并在静脉相与周围组织同步(12例)或稍快消退(9例),差异有统计学意义(P<0.05)。结论超声造影对低位胆道梗阻定性诊断有一定参考价值。Objective To investigate the application value of contrast-enhanced ultrasound（CEUS） in the differential diagnosis of benign and malignant low biliary obstruction lesions. Methods The results of contrast-enhanced ultrasound and enhanced pattern of 53 inpatients with low biliary obstruction diagnosed by pathology were retrospectively analyzed. The accuracy, specificity,sensitivity,positive predictive value and negative predictive value of CEUS in the diagnosis of biliary obstruction malignant lesions were calculated,and CEUS characteristics of benign and malignant lesions were summarized. Results The accuracy,sensitivity,specificity,positive predictive value and negative predictive value of CEUS in the diagnosis of malignant lesions were 94.3%,92.3%,96.3%,96.0% and 92.9%,respectively. The malignant lesions were manifested as inhomogeneous enhancement（21 cases） or equal enhancement（3 cases） in the arterial phase,and a significant decrease in venous phase. The benign lesions were manifested as equal enhancement（21 cases） in the arterial phase,synchronization（12 cases） and slight significant decrease（9 cases） in venous phase,there was significant difference（P〈0.05）. Conclusion CEUS has some reference values in the qualitative diagnosis of low biliary obstruction.
