摘要
目的探讨实时灰阶谐波超声造影和动态增强螺旋CT对肝局灶性病变的诊断价值。方法选择肝局灶性病变患者49例,共54个病灶。其中包括原发性肝癌29个,转移性肝癌4个,肝血管瘤11个,肝局灶性结节增生7个,肝硬化结节1个,肝脂肪浸润不均2个。分别进行实时灰阶谐波超声造影和动态增强螺旋CT检查,比较肝肿瘤在两种成像方法中的表现。结果两种成像方法显示的肝肿瘤在不同时相的表现及在动脉相的增强类型相一致。超声造影鉴别诊断肝良恶性病变的敏感性、特异性和准确性分别为90.9%(30/33)、90.5%(19/21)和90.7%(49/54);动态增强螺旋CT鉴别诊断肝良恶性病变的敏感性、特异性、准确性分别为90.9%(30/33)、95.2%(20/21)和92.6%(50/54),二者鉴别肝局灶性病变良恶性的能力差异无显著性意义。结论实时灰阶谐波超声造影和动态增强螺旋CT均能反映肝病变的血流动力学特性,均有助于肝肿瘤的鉴别诊断。
Objective To compare enhancement features of hepatic tumors on SonoVue-enhanced real-time gray-scale ultrasonography and contrast-enhanced helical CT. Methods SonoVue-enhanced realtime gray-scale ultrasonography and contrast-enhanced helical CT were performed on 49 patients with 54 focal liver lesions, including 29 primary liver carcinomas, 4 metastatic liver tumors, 11 hepatic carvernous hemangiomas, 7 focal nodular hyperplasias, 2 focal fatty sparing, 1 cirrhotic. Results Contrast-enhanced ultrasonography and helical CT showed consistent results in demonstrating hemodynamics of hepatic tumors. In the differentiating of malignant tumors and benign tumors, the sensitivity, specificity and accuracy of contrast-enhanced ultrasonography were 90.9% （30/33）, 90.5% （ 19/21 ） and 90.7% （49/54）, respectively. Those of contrast-enhanced CT were 90.9% （30/33）, 95.2% （20/21） and 92.6% （50/54）, respectively. Conclusions Both of the two imaging methods are valuable for differential diagnosis of liver tumors.
