周围型小肺癌的X线诊断

Radiodiagonsis of Small Peripheral Lung Cancer

目的分析周围型小肺癌胸部平片特征,探讨早期发现周围型小肺癌的X线检查方法。方法搜集15例均由病理证实的周围型小肺癌,所有病例均采用低千伏感蓝片X线摄影与高千伏感绿片X线摄影,并采用体层摄影进行观察相对照。结果低千伏感蓝片X线摄影发现病灶率平均为55%,诊断正确率平均为30%,采用高千伏感绿片摄影技术病灶平均发现率平均为80%,诊断正确率平均为42%,结合体层摄影观察诊断正确率平均为67%。结论采用高千伏感绿片摄影结合体层摄影技术,明显提高周围型小肺癌的发现率及诊断准确率。

Objective To analyze the chest radiography character of small peripheral lung cancer and investigate the methods of chest radiography by which might detect it early. Methods Gathering 15 cases of small peripheral lung cancer all be proved by pathology. All cases preceed low kV radiography with blue fil and high kV radiography with green fil, further all proceed tomography then compared them. Results It＇s only averge 55% that to find the small peripheral lung cancer and diagnosis correctly is 30% by low kV radiography with blue ill,it＇s 80% and 42% by high kV radiography with green fil ; it＇s averge 67% that diagnosis correctly if the latter combining tomography. Conclusion It can improve no tably the rate of finding and diagnosing correctly the small peripheral lung cancer by high kV radiography with green fil and combining the tomography.
