【摘要】 目的　评价在超声导向微波凝固治疗肿瘤前作利声显超声造影的鉴别诊断价值。方法　 2 0例临床诊断为恶性肿瘤的患者 ,经周围静脉注射利声显作超声造影和超声导向经皮穿刺活组织检查 ,作对照分析。结果　 2 0例中 12例确诊为肝癌、1例为转移性肺癌 ,7例确诊为良性病变。恶性病变造影后病灶区血管增强为 2～ 3级、呈动脉相或混合相增强图像、时间 强度曲线呈高抛型 ;良性病变病灶区血管增强为 0～ 1级、呈静脉相增强图像、时间 强度曲线呈低平型。结论　利声显超声造影对超声导向微波凝固治疗前 ,肿瘤良恶性的鉴别诊断有显著价值更多还原

【Abstract】 Objective To evaluate the role of Levovist contrast ultrasound in the differential diagnosis of tumors before US guided microwave coagulation therapy. Methods 20 patients with malignant tumor were analyzed with Levovist contrast ultrasound and US guided percutaneous biopsy.Results 12 patients were diagnosed as liver cancer, 1 lung metastases, 7 benign mass. After injected agent, artery wave or mixed wave of malignant lesions were enhanced 2～3 grades, time intensity curves show high parabola; but in benign lesions only enhanced 0～1 grades were showed and, vein wave as well as low level time intensity curve.Conclusion Levovist contrast US plays a great role in differentiating malignant tumor from benign tumors before microwave coagulation therapy.
