目的 通过分析CT影像上肺癌灶内钙化特点提高其诊断率。方法 对 2 5例经病理证实的肺癌灶内钙化从CT影像上进行了形态、数目、分布的研究。结果 钙化呈孤立偏心点状 15例 ,散在的小结节状 4例 ,弥漫不规则斑片状 6例。多发钙化累及病灶 1/ 3以下的 3例 ,1/ 2的 2例 ,2 / 3以上的 5例。结论 肺部肿块内钙化为孤立偏心点状时结合病灶其他特点应高度警惕肺癌
Objective To improve the diagnostic rate of lung cancer by analyzing the features of calcification in CT images. Methods The morphology, number and distribution of calcification in 25 cases of pathologically confirmed lung lesions were studied. Results Calcification was isolated eccentric point in 15 cases, scattered nodules in 4 cases, diffuse irregular patchy in 6 cases. Multiple calcifications affected lesions in 1/3 of 3 cases, 1/2 in 2 cases, 2/3 or more in 5 cases. Conclusion Pulmonary intraluminal calcification of isolated eccentric point-like lesions combined with other characteristics should be highly vigilant lung cancer
