摘要
目的:比较X线与CT检查对肺癌的诊断价值。材料与方法:100例肺癌经X线平片和断层摄影及CT检查,并与手术病理对照。结果:中心型肺癌48例,其中CT确诊42例(87.5％),而X线确诊34例(70.8％),显然,CT优于X线。就周围型肺癌而言,在显示肿块分叶状与毛刺状方面,CT类似于X线,当调整肺窗与纵膈窗的窗宽与窗位时,CT比X线显示得清晰。经手术病理证实,肺门、纵膈淋巴结转移67例,CT检出其中48例(72％),而X线只检出16例(24％)。然而,在显示肿物整体形态及边缘状况方面,常规X线胸片及病灶体层片却又比CT好些。结论:X线与CT两种检查方法对肺癌诊断各有利弊,要正确合理配合应用来提高肺癌的诊断水平。
Purpose: To compare the diagnostic value of roentgenography and CT for pulmonary carcinoma. Materials and Methods: One hundred patients with pulmonary carcinoma underwent both examinations from X-ray plain film and CT, and compared with post - operative pathology. Results: 48 cases were proved by pathology to be central - type pulmonary carcinoma, of them, 42 cases were accurately diagnosed on CT and 34 cases were accurately diagnosed on X-ray chest film, their diagnostic accuracy were 87. 5% and 70. 8% , respectively. In the case of peripheral lung carcinoma, the lobulated and the spiculated of the mass displayed with CT were similar to that with X - ray chest film, but when the width and the level of pulmonary window and me-diastinal window were adjusted, the displays of lesions on CT were superior to X - ray. In addition, 67 patients with metastasis from lymphatic nodes in the hilum of lung and mediastinum proved by pathology, of them, CT detected - out 48 cases(72%)but X - ray detected out only 16 cases(24%). Contrarily, the whole form and edge state of mass revealed with conventional X - ray chest film and sectional roentgenography were better than that with CT. Conclusion: Each of X - ray and CT in the diagnosis of pulmonary carcinoma has its advantages and lacks, if only these two examinations are joined together rightfully and reasonably, the diagnostic level will be elevated.
