Value of MSCT and X-ray in the Diagnosis of Pneumothorax
Objective To observe the value of multi-slice spiral CT(MSCT)and X-ray in the diagnosis of pneumothorax.Methods 100 patients with pneumothorax admitted to Yulin Second Hospital in Shaanxi Province from May 2021 to May 2022 were selected as the study subjects.All of them received MSCT and X-ray examinations,and their imaging characteristics were analyzed.MSCT was taken as the golden standard for diagnosing pneumothorax to analyze the diagnostic consistency of X-ray.Results Under MSCT primary spontaneous pneumothorax showed flat thorax,internal process of rib,emphysema-like changes and pleural stomata.38 pleural windows were detected in 21 patients,including 15 on the left side and 6 on the right side.Most of them were observed at the apex of lung,followed by anterior chest wall and mediastinum.MSCT found slight pneumothorax in 72 cases and massive pneumothorax in 28 cases.Chest X-ray films showed that the transparency of both lungs of patients with pneumothorax was enhanced,patchy high-density shadows were observed in both lungs,and lung tissues were compressed and gathered.There were 9 cases without hemopneumothorax,68 cases of slight pneumothorax and 23 cases of massive pneumothorax.The lung compression ratios measured by MSCT for slight pneumothorax and massive pneumothorax were higher than those measured by X-ray(P＜0.05).For lung compression ratio of slight pneumothorax,the correlation between X-ray and MSCT reached 0.904(P＜0.05).For massive pneumothorax,the correlation was 0.918(P＜0.05).Consistency test found that there was a high consistency between X-ray and MSCT in the diagnosis of massive pneumothorax(Kappa value=0.705).Conclusion Both MSCT and X-ray can be used to diagnose pneumothorax,and the performance of MSCT is better.It can provide reliable basis for clinical selection of treatment.
