超声造影对肝脏局灶性病变的诊断价值

目的：探讨超声造影对肝脏局灶性病变的诊断价值。方法：采用低机械指数实时连续成像技术和造影剂SonoVue对149例肝脏局灶性病变作超声造影检查。结果：149确肝脏局灶性病变中，肝脏恶性肿瘤具有较特征性的超声造影表现，而良性病变除血管瘤、局灶性增生结节、肝脏囊性占位具有特征性的改变易于诊断外，其他尚无特征性表现。结论：超声造影对肝脏局灶性病变具有较高的诊断价值，尤其是鉴别良恶性病变。

Diagnostic value of contrast enhanced ultrasound in focal liver lesion

Objective： To explore the diagnostic value of contrast enhanced ultrasound （CEUS） in focal liver lesion. Methods： SonoVue was injected in 149 patients with focal liver lesion, and the technique of CEUS was performed. The enhancement features were observed. Results： 149 cases with focal liver lesion were detected. Malignant focal liver lesions had characteristic contrast pattern, and were easy to be diagnosed. However the benign focal liver lesions had no characteristic contrast pattern except some diseases, such as hemangiomas and FNH. Conclusions： Contrast enhanced ultrasound has high value in diagnosing focal liver lesion, especially in differentiating malignant or benign focal liver lesions.
