摘　　要：目的:探讨低机械指数谐波超声造影在局灶性肝脏病变治疗适应证选择中的应用价值。方法:对232例(共357个结节)局灶性肝脏病变患者进行低机械指数谐波超声造影、增强CT/MR和/或病理检查。结果:低机械指数谐波超声造影诊断肝脓肿10例,患者行超声导向穿刺抽脓、局部注药治疗;诊断恶性肿瘤147例,其中82例行非手术治疗,包括7例行经皮无水乙醇注射治疗,57例行射频消融或微波凝固治疗,14例行肝动脉化疗栓塞或经皮无水乙醇注射治疗联合射频消融,4例行肝动脉化疗栓塞。结论:超声造影有助于肝脏局灶性病变治疗适应证的选择。Objective： To evaluate the value of contrast-enhanced harmonic sonography with low mechanical index in choosing the treatment indicator of focal liver lesions. Methods： Two hundred and thirty-two patients with 357 focal liver lesions were examined by contrast-enhanced harmonic sonography with low mechanical index, contrast-enhanced CT/MR and/or pathological examination. Results： Ten patients with liver abscess were confirmed by contrast-enhanced harmonic sonography with low mechanical index and treated by percutaneous puncture. One hundred and forty-seven patients with malignant tumor were diagnosed by contrast-enhanced harmonic sonography with low mechanical index. In which, 82 patients were treated by non-operative therapy. Percutaneous ethanol injection was carried out in 7 cases. Radiofrequency ablation or microwave coagulation therapy was performed in 57 cases. Transcatheter arterial chemoembolization or percutaneous ethanol injection combined with radiofrequency or microwave ablation was performed in 14 cases. Four patients were only treated by transcatheter arterial chemoembolization. Conclusions： Contrast-enhanced harmonic sonography with low mechanical index is helpful for choosing the treatment indicator of focal liver lesions.
