Abstract: Aim of this study was to investigate the relationship between CT imaging characteristics and inflammatory condition and treatment outcome in patients with bacterial infectious pneumonia. One hundred patients who were clearly diagnosed with bacterial infectious pneumonia by pathogenic examinations were selected as the bacterial group, and 100 patients with viral infectious pneumonia confirmed by serological examinations during the same period were selected as the virus group. The imaging characteristics of the two groups of patients in the advanced stage of the CT examination were compared. According to the critical condition of the patients, the bacterial group was divided into high-risk and intermediate-risk groups, and the bacterial group was divided into survival and death groups according to the 28-day treatment outcome, and compared Differences in lung CT features. In the incidence of lung lobe consolidation and CT signs of aerated bronchial sign, the bacterial group was higher than that of the virus group (P<0.05). As to the comparison of the detection results of ground glass shadow characteristics of the lungs, the bacterial group was lower than the virus group (P<0.05). The detection rate of lung lobe consolidation, lung segment consolidation, pulmonary ground glass shadow, pleural effusion, and air bronchial signs in the high-risk group were higher than those in the intermediate-risk group (P<0.05). The incidence of lung lobe consolidation, segment consolidation, and pleural effusion in the death group were higher than those in the survival group (P<0.05). The death group and the survival group had lung glass shadows, mesh strips, and air-filled bronchial signs. There was no statistically significant difference in incidence (P>0.05). According to the characteristics of chest CT examination, the type of pathogen can be identified to a certain extent, and it has certain reference value for the disease degree and prognosis evaluation of patients with bacterial pneumonia.
