Feasibility study of imaging diagnosis of diabetes mellitus patients with pulmonary tuberculosis

Objective: To analyze the feasibility of CT diagnosis for patients with diabetes mellitus (DM) and pulmonary tuberculosis (PTB). Methods: A total of 120 DM patients with PTB in our hospital were included in the combination group, and 50 patients with PTB were included in the PTB group. CT examination was performed in all patients and the diagnostic value of CT was analyzed. Results: No significant difference was found in PTB lesions between the combination group and PTB group (P > 0.05). The incidence rates of cavities, necrosis and caseous pneumonia in the combination group were higher than those in the PTB group (P < 0.05). In the combination group, the ratios of tuberculosis (TB) in a single pulmonary lobe and two or more pulmonary lobes were 33.33% and 66.67% respectively, while those were 54.00% and 46.00% respectively in the PTB group (P < 0.05). No significant difference was found in the number of pulmonary segments in the classification of good, general and poor glycemic control effects (P > 0.05). Significant differences were found in the incidence of large flakes of segmental and lobar shadows, bronchial inflation signs, wall-less cavities, multiple cavities, thick-walled cavities, and bronchial TB among classification of good, general and poor glycemic control effects (P < 0.05). Conclusion: There are certain differences in CT manifestations between patients with both DM and PTB and patients with PTB. There are certain differences in CT manifestations among DM patients with PTB with good, general and poor glycemic control effects. These results exhibit that when using CT for diagnosis of whether DM patients have PTB can be performed and the glycemic control effects on DM patients can be identified.
