摘　　要：目的:评价薄层CT对肺气肿合并肺大疱的诊断价值。方法:对60例肺气肿合并肺大疱病例进行1.0 mm薄层CT重建,并与5.0 mm常规厚层CT扫描比较。图像分析共分2组,2人2次完成阅片。结果:60例患者中,轴位常规CT和薄层CT仅对同1例患者没有诊断出肺大疱,常规CT中有19例没有发现全部小于1 cm的肺气肿,另有11例只显示部分小于1 cm的肺气肿。结论:目前采用重建1.0 mm层厚的薄层CT图像在评价肺大疱的数量能力等同于厚层CT,薄层CT则显示了其余全部的小于1 cm的肺气肿、肺大疱。薄层CT在评价肺气肿的数量、肺气肿和肺大疱细节的能力优于厚层CT。Objective: To evaluate the value of thin-slice CT in the diagnosis of emphysema complicated with bulla. Methods: 60 cases of emphysema complicated with bulla were reconstructed by 1.0 mm thin-slice CT and compared with 5.0 mm thick slice CT. The image analysis was divided into 2 groups. 2 people read the images twice. Results: Among the 60 patients, only 1 patient was not diagnosed with bullosa by conventional axial CT and thin-slice CT. 19 patients were not found with emphysema smaller than 1 cm in total, and 11 patients were only found with emphysema smaller than 1 cm. Conclusion: At present, thin-slice CT images with 1.0 mm thickness reconstruction are equivalent to thick slice CT in the quantitative evaluation of pulmonary bulla, and thin-slice CT shows all other emphysema and pulmonary bulla less than 1 cm. Thin-slice CT was superior to thick slice CT in evaluating the number of emphysema and the details of emphysema and bulla.
