摘　　要：目的:探讨对比16层螺旋CT低剂量薄层技术与常规胸片对肺部病变的检出率。方法:选取肺部疾病患者120例,随机将其分为16层螺旋CT低剂量薄层肺部检查组和常规胸片肺部检查组,每组60例,对比两组的病变检出率。结果:16层螺旋CT低剂量薄层技术检查组查出肺纤维化8例,肺气肿6例,肺结核5例,肺癌2例,共计肺部疾病21例(占35.00%);而常规胸片肺部检查出肺纤维化2例,肺结核1例,肺癌2例,共计肺部疾病5例(占8.33%)。16层螺旋CT低剂量薄层肺部检查组与常规胸片肺部检查组病变检出率差异有统计学意义(x2=12.5696,P<0.05)。结论:16层螺旋CT低剂量薄层肺部检查组比常规胸片肺部检查组对病变检出率高,可有效检出肺部疾病,且对患者和医护人员的辐射损伤小,可以广泛应用。Objective： To explore and analyze detection rate of lung lesions of 16 slice spiral CT low dose of TLC technique and conventional radiography. Methods： Selected 120 lung disease patients in our hospital, they were randomly divided into 16 layers of low dose spiral CT examination examination group and conventional thin chest lung examination group, each group had 60 patients,compared two groups＇ detection rate of contrast. Results： 16 thin layer of low-dose spiral CT technology inspection found 8 pulmonary fibrosis patients, including 6 emphysema patients, 5 tuberculosis patients, 2 lung cancer; there were 21（35%.00） lung disease in total.While conventional chest X-ray examination revealed 2 pulmonary fibrosis, 1 man tuberculosis, 2 lung cancer.There were 5（8.33%） lung disease in total. The detection rates of 16 slice spiral CT low dose of TLC examination of lung and conventional radiography examination of lung lesion had differences（x2=12.5696, P0.05）. Conclusion： 16 slice spiral CT low dose of TLC inspection has higher detection rate compared with the conventional chest X-ray examination on lung lesions,it can exam lung disease effectively, its radiation damage on physical examination and medical staff is small, and can be widely applied, it is worth to popularize.
