| 摘 要： | 目的:利用低剂量CT,降低X线照射量,减少对人体辐射的方法开展对早期无症状肺癌的筛查,提高检出率,实现疾病的早期诊断和治疗,提高生存率。改善肺癌长期以来发病隐蔽诊断难的状况。方法:对500例无胸部症状人群分吸烟组和非吸烟组,应用低剂量扫描参数,对病灶局部加用HRCT及图像后处理技术等,进一步提高早期肺癌的检出率。结果:500例受检人群中筛查出大小结节35例,其中确诊肺癌6例、良性病变7例(错构瘤2例,结核球2例,炎性肿块3例),余22例为阴性结节。有87例为其他肺部疾病(肺气肿、肺大泡、炎症、陈旧性结核、胸腔积液、胸膜肥厚等)。378例为正常。6例肺癌分别做了手术、放疗、化疗等治疗。结论:低剂量CT是检测早期无症状肺癌有效的方法,可提高检出率,实现疾病的早期诊断和治疗。

| Abstract: | Objective：To utilize the method of low-does CT to reduce the exposure to X-ray,to reduce the radiation to the human body,to carry out the screening on primary asymptomatic lung cancer,to increases the screening rate,to realize the early diagnosis and treatment against disease and to increase the survival rate.It improves the situation that has been for a long time,in which the lung cancer attacks unnoticeably and is difficulty to be diagnosed.Method：To divide 500 cases having no symptom in the chest into two groups：smoking group and non-smoking group.Aided by employing the HRCT Image Post-processing Technology in the local lesion,low-does scanning parameter was applied in increasing the screening rate of primary lung cancer.Result：35 cases were confirmed to be carrying tubercle out of 500 cases,among which 6 cases were confirmed as lung cancer;7 cases as benign lesion（2 cases as hamartoma,2 cases as tuberculoma and 3 cases as inflammatory masses） while the remaining 22 cases were confirmed as negative tubercle.Besides,87 cases were confirmed as other types of lung disease（emphysema,bulla of lung,inflammation,obsolete tuberculosis,hydrothorax,pachynsis pleurae,etc.） and 378 cases are normal.The 6 lung cancer cases were given surgery,radiotherapy,chemotherapy,etc.respectively.Conclusion：The low-does CT,which can increase the screening rate and realize the early diagnosis and treatment against disease,is an effective method to detect primary asymptomatic lung cancer. |
