Abstract:
Objective:To investigate the value of CT multiplanar reconstruction (MPR) in the diagnosis of stage Ⅲ pneumoconiosis and complications.Methods:In September 2020, 94 patients with stage Ⅲ pneumoconiosis in Guangzhou 12th people's hospital were selected for digital radiography (DR) and MPR. The detection rate of the number of large shadows and the incidence of related complications were compared and analyzed. The counting data were expressed by frequency and percentage (%) , and the comparison was performed by chi square test.Results:178 and 132 large shadows were detected in MPR and DR chest films respectively. Compared with Dr examination, MPR had higher detection rates of pneumoconiosis related complications such as pulmonary tuberculosis, emphysema, pleural thickening, adhesion, pneumonia, pleural effusion, enlargement of hilar and mediastinal lymph nodes and calcification ( P<0.05) , There was no significant difference in the detection rate of pulmonary bullae ( P>0.05) . Compared with Dr, MPR had a higher detection rate in the diagnosis of cavity, calcification, bronchiectasis and parascar emphysema ( P<0.05) . Conclusion:MPR is better in detecting large shadow and complications of stage Ⅲpneumoconiosis, and has important value.
