目的探讨超声造影在肺周围型局灶病变中的应用价值。方法 50例肺周围型局灶病变患者,50个病灶行常规超声、超声造影检查,分别按常规超声评分标准、超声造影评分标准对病灶进行评分,比较两组评分标准在鉴别肺周围型局灶病变良、恶性方面的研究价值。结果经ROC曲线分析,常规超声评分标准曲线下面积为0.878,当评分≥6分,其在鉴别肺周围型局灶病变良、恶性的灵敏度、特异度分别为63.0%、95.7%(P<0.01,95%置信区间);超声造影评分标准曲线下面积为0.894,当评分≥5分,其在鉴别肺周围型局灶病变良、恶性的灵敏度、特异度分别为70.4%、82.6%(P<0.01,95%置信区间)。结论超声造影在鉴别肺周围型局灶病变良、恶性方面的研究价值要大于常规超声。
Objective To explore the value of contrast-enhanced ultrasound in focal lesion of the lung. Methods Fifty patients with focal lesions of the lung and 50 lesions underwent routine ultrasound and contrast-enhanced ultrasound examinations. The lesions were scored according to the standard ultrasound and the contrast-enhanced ultrasound, respectively. The scores of the two groups were compared between the two groups Good disease, malignant research value. Results According to the ROC curve analysis, the area under the standard curve of routine ultrasound was 0.878. When the score was ≥ 6, the sensitivity and specificity of differentiating pulmonary lesions were 63.0% and 95.7% (P <0.01, respectively) , 95% confidence interval). The area under the standard contrast echocardiography score was 0.894. When the score was ≥5, the sensitivity and specificity of the method were 70.4% and 82.6% 0.01, 95% confidence interval). Conclusions The value of contrast-enhanced ultrasound in the diagnosis of benign and malignant lesions of peripheral lung is better than that of conventional ultrasound.
