【摘要】 目的:探讨超声造影(CEUS)在肝细胞性肝癌(HCC)诊断和鉴别诊断中的应用价值。方法:对58例肝脏局灶性病变进行超声增强造影检查并观察动脉相、门脉相和实质相的动态造影变化,对不同性质的病变的造影特点进行了分析总结。结果:造影结果诊断34例HCC中34例均经病理或AFP证实,33例具有造影剂的快进快出及动脉相均匀性或非均匀性增强的特点。超声造影在HCC中的快进快出即动脉相快速增强,门脉相和实质相快速消退的特点并具有较高诊断敏感性(97%)和特异性(99%)。结论:超声造影在肝脏局灶性异常回声的筛选诊断及鉴别诊断中具有重要的临床意义和应用价值。更多还原

【Abstract】 Objective: To assess the value of contrast-enhanced ultrasonography in the diagnosis of HCC. Method: Dynamic changes in different phases were studied during the contrast-enhanced ultrasonic examination in 58 cases. Results: HCC were characterized by quick wash-in and wash-out(high and rapid peak of enhancement in the arterial phase, followed by a relative quick wash-out in the portal phase) and homogeneous or inhomogeneous enhancement with contrast-enhanced US(chaotic peri-tumoral and intra-lesional tortuous vessels and irregular vascular lakes). Conclusion: Contrast-enhanced US in the diagnosis of HCC is of high sensitivity and specificity.更多还原
