Comparison and research on detection rate of lung lesions of 16 slice spiral CT low dose of TLC technique and conventional radiography / 中国医学装备

ABSTRACT

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, P<0.05). 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.
