外围型肺癌的CT鉴别诊断

对１００例经手术病理证实之肺内良、恶性结节的临床、ＣＴ与病理表现进行了回顾性分析，结合文献复习对分叶、棘状突起、空气支气管征、血管连接及胸膜凹陷等征象的诊断价值进行评估，认为外围型肺癌的影像表现复杂多变，重视窗口技术，充分显示病灶细节，认准病理征象，综合分析诊断，可提高对肺良、恶性结节的诊断准确率。笔者提出以病灶直径分组分析，可缩小外围型肺癌的鉴别诊断范围。

DIFFRENTIAL DIAGNOSIS OF CT IN THE PERIPHERAL LUNG CANCER

The author studied retrospectively the clinic CT and pathology of 100 cases with pulmonary solitary nodule proved pathologically,also reviewed lobulation,spiculation,spiculated protuberance, air bronchogram and pleural retraction.Results showed that CT appearances of peripheral lung cancer were very confusing.Setting technicality of proper window,displaying details of lesion,and grasping the signs of image can increase the diagnostic accuracy of pulmonary solitary nodule.The author concluded that grouping by size of lesion can reduce difficulties in differentiating the peripheral lung cancer from other lung diseases.
