原发性肺癌的影像学诊断

To diagnose primary lung cancer by means of X-ray

目的:提高医学影像学检查对原发性肺癌诊断的认识。方法:回顾性分析138例经手术和病理证实的原发性肺癌的X线、CT及高分辨CT(HRCT)征象,评价影像学诊断的临床应用价值。结果:138例原发性肺癌中,中央型肺癌91例,表现为肺不张、肺门肿块、支气管狭窄等。周围型肺癌43例,表现为肿块常为分叶状、毛刺及胸膜凹陷等。弥散型肺癌4例,表现为两肺弥漫结节阴影等。结论:原发性肺癌影像学表现有一定特征,尤其是HRCT可以较准确反映原发性肺癌的病理特征,是诊断原发性肺癌的有效手段。

Purpose： To improve the imaging diagnosis of primary lung cancer and discuss its clinical value. Methods： 138 eases of primary lung cancer were retruspectively analyzed, combined with operation and pathology and clinical follow- up by means of X- ray,Cr and HRCT.Restults： Among them including central - style lung cancer（91 cases） ,the major imaging feature： pulmonary atelectasis; pulmonary hilar mass; bronchial stenosis, peripheral - style lung cancer （ 43 cases ）, the major imaging feature： majority of mass - forming is lobulation; speculation; pleural indentation. Diffusion - style lung cancer （ 4 cases）, the major inaging feature：two lung field diffuse nodular patterns. Conclusion： The primary lung cancer possess relative imaging feature, particularly. HRCT may accurately reflect pathological feature of the primary lung cancer, would be considered as effective method for diagnostic purpose.
