隐蔽部位肺癌X线与CT诊断价值的比较

目的：比较常规X线检查与CT对肺隐蔽部位较小肺癌的诊断率，方法：对临床已证实的30例肺隐蔽部位肺癌病人，分别做X线平片，体层摄影和CT检查，评估常规X线与CT对病变的显示能力，结果：胸部平片检出病灶12例（40％），CT检出30例（100％），结论：平片与CT在诊断肺隐蔽部位肺癌时，尤其直径为2cm以下的小肺癌，CT明显占优势，对临床症状明显，平片检查阴性者，CT检查必不可少。

Comparasion ofconventional radiography with computed tomography in hide place of lung cancer

Objective:To compare the diagnosed values of conventional X-ray plain film and CT in detecing lung cancer in hide place. Methods: 30 cases of lung cancer in hide place confirmed by operation and pathology were collected. To study the diagnosed value by radiography and CT, two methods for this entity were analysed and compared. Results: 12 cases of lung cancer in hide place were showed by plain film (40%), 30 cases by CT(100%).Conclusion: CT has advantage of demonstrating small tumor that conventional radiography may miss, for small lung cancer less than 2 cm CT is able to diagnose qualitively, CT examine is very necessary for patient who is suspected suffering from lung cancer.
