Objective:To conduct in-depth research on the clinical effectiveness of using multi-slice spiral CT for differential diagnosis of pulmonary tuberculosis and lung cancer cavities. Methods:This study selected 93 patients diagnosed with pulmonary tuberculosis and lung cancer in our hospital as the subjects. All patients underwent multi-slice spiral CT examination. The patients with pulmonary tuberculosis cavity were in the pulmonary tuberculosis group (n=57),while the patients with lung cancer cavity were in the lung cancer group (n=36). Compare the location,nature,surrounding tissue characteristics,and size of cavity lesions between the two groups of patients. Results:The proportion of upper lobe voids in patients with pulmonary tuberculosis was higher than that in patients with lung cancer,while the proportion of lower lobe voids in patients with pulmonary tuberculosis was lower than that in patients with lung cancer. After comparing the data between the two groups,the difference was significant (P<0.05);There was no significant difference in the proportion of middle lobe/lingual cavity between the two groups of patients (P>0.05). The length and diameter of cavities in the lung cancer group were longer than those in the tuberculosis group,and the number of thick walled cavities in patients was higher than that in the tuberculosis group. After comparing the data between the two groups,the difference was significant (P<0.05). The incidence of calcification in patients with pulmonary tuberculosis was higher than that in patients with lung cancer. The probability of nodules,burrs,and lobulation in patients with lung cancer was higher than that in patients with pulmonary tuberculosis. After comparing the data between the two groups,the difference was significant (P<0.05). The probability of peripheral tissue inflammation,satellite lesions,and lymph node calcification in patients with pulmonary tuberculosis was higher than that in patients with lung cancer. After comparing the data between the two groups,there was a significant difference (P<0.05),while the difference in the probability of pleural adhesions between the two groups was not significant (P>0.05). The proportion of type Ⅲ patients in the tuberculosis group was higher than that in the lung cancer group,and the proportion of type IV patients was lower than that in the lung cancer group. After comparing the data between the two groups,the difference was significant (P<0.05),while the proportion of type Ⅰ and type Ⅱ patients in the two groups was not significant (P>0.05). Conclusion:The use of multi-slice spiral CT examination has significant differences in the characteristics of pulmonary tuberculosis and lung cancer cavities,including lesion nature,size,surrounding tissue level,location,and morphology. It can effectively differentiate and diagnose the source of pulmonary cavity patients.
