Objective:To explore the application value of low-dose multi-slice spiral CT scanning and serum carbohydrate antigen(CA153)and squamous cell carcinoma antigen(SCC)tests in distinguishing pulmonary inflammatory and cancerous nodules.Methods:100 suspected lung cancer patients admitted to our school's direct and non direct affiliated hospitals from January 2021 to January 2023 were selected.All patients underwent low-dose multi-slice spiral CT,serum CA153,and SCC examinations.The diagnostic gold standard was the pathological results of lung biopsy.The application value of low-dose multi-slice spiral CT scanning,serum CA153,and SCC examinations in the differential diagnosis of pneumonia and cancerous nodules was analyzed.The results were confirmed by pathological examination of lung biopsy tissue.Results:The accuracy,sensitivity,and specificity of low-dose multi-slice spiral CT scanning in differential diagnosis of lung cancer patients were 89.00%,91.07%,and 86.36%,respectively.The results showed that low-dose multi-slice spiral CT scanning,serum CA153,and SCC tests had an AUC of 0.887,0.845,and 0.843 for the diagnosis of pneumonia and lung cancer nodules.Conclusion:Low dose multi-slice spiral CT scanning has high clinical value in differential diagnosis of lung cancer nodules and pneumonia benign nodules.
