Abstract Objective To explore the diagnostic value of 64 slice spiral CT low dose chest scan in lung cancer patients.Methods A total of 100 patients suspected with lung cancer admitted to our hospital from February 2017 to February 2019 were selected as the research objects. All patients were examined by direct digital X-ray radiography system (DR) and 64 row spiral CT low-dose chest scanning. The detection rate, lung sign detection, sensitivity, specificity and image quality of the two methods were compared. Results Of the 100 patients, 96 were diagnosed as lung cancer by pathology and 4 were non lung cancer. A total of 85 cases of lung cancer were confirmed by DR chest film. 95 cases of lung cancer were diagnosed by low dose chest scan with 64 slice spiral CT. The sensitivity (98.96%) and accuracy (98.00%)of 64 row spiral CT low-dose chest scanning were higher than those of DR chest film examination (88.54% and 86.00% ), the differences were statistically significant (P ＜0.05)； the detection rate of hilar and mediastinal lymphadenopathy of 64 row spiral CT low-dose chest scanning was higher than that of DR chest film examination, the difference was statistically significant (P＜0.05). There were no significant differences in the detection rates of pleural effusion, vacuole sign and bronchial symbol, pleural indentation sign, thick wall cavity, burr sign and lobulation sign between the two methods (P＞0.05). The excellent and good image quality rate of 64 slice spiral CT low-dose chest scan(98.00%) was higher than that of DR chest film (85.00%), the difference was statistically significant (P ＜0.05).Conclusion Low dose chest scan with 64 slice spiral CT can significantly improve the accuracy of lung cancer diagnosis, and the image quality is high, which is worth learning.

Key words： Lung cancer DR chest film 64 slice spiral CT Low dose chest scan
