【摘要】 目的 探讨超声对肺肿瘤的诊断价值和肿瘤声像图特征。 方法 应用超声检查肺肿瘤患者239例。 结果 超声对胸腔积液、肺不张的敏感性为100%，对肺实变内肿块检出率为90.38%。声像图特征表现为:(1)小肿块回声呈低等状。(2)较大的肿块内回声呈强光点或平行双线强光带。 结论 超声检查对肺肿瘤有辅助诊断价值，可作为肺肿瘤的一种检查手段。

    【Abstract】 Objective To investigate the diagnostic value and sonographic appearance of lung neoplasm by ultrasonography(US)examination.Methods US imaging were performed to239cases of lung neoplasm.Results The sensitivity of US imaging to atelectasis and pleural effusion is100%;the sensitivity to masses in atelectasis is90.38%.The sonographic appearances were summarized as:1)the echo of smaller masses is low density;2)the e-cho of bigger masses is strong light spots or strong light belt appears as parallel double lines.Conclusion US imaging is useful for detection of lung neoplasms.
