摘　　要：目的:探讨数字X线成像(DR)联合双能量减影技术(DES)在尘肺病诊断中的临床应用价值。方法:选取尘肺病病人共102例,分别使用DR联合DES及胶片-增感屏X线摄影技术(FSR)拍摄全胸片,比较两种摄片方法胸片图像质量及诊断信息。结果:DR联合DES的优片率、良片率、差片率、废片率分别为96.08%、3.92%、0.00%、0.00%,FSR的优片率、良片率、差片率、废片率分别为72.55%、16.67%、7.84%、2.94%,DR联合DES优片率明显高于FSR(P<0.01)。DR联合DES共检出壹期以上尘肺病病人81例,检出率为79.41%;FSR共检出壹期以上尘肺病病人61例,检出率为59.80%;DR联合DES尘肺病检出率高于FSR(P<0.05)。DR联合DES对纵隔淋巴结肿大、肺部感染、肺气肿、胸膜增厚的检出率高于FSR(P<0.05~P<0.01)。DR联合DES检测同期别尘肺病小阴影分布范围大于FSR。结论:DR联合DES具有更佳的图像质量表现和检出率,可应用于尘肺病的检查及诊断。Objective:To explore the clinical application value of digital radiography(DR)combined with dual-energy subtraction(DES)in the diagnosis of pneumoconiosis.Methods:A total of 102 patients with pneumoconiosis were selected and underwent both DR combined with DES and film-screen radiography(FSR)to take the whole chest radiography.The image quality and diagnostic information of the two techniques were compared.Results:The rate of excellent film,fine film,poor film and waste film of DR combined with DES was 96.08%,3.92%,0.00%and 0.00%,respectively;which of FSR was 72.55%,16.67%,7.84%and 2.94%,respectively;the rate of excellent film of DR combined with DES was significantly higher than that of FSR(P<0.01).Eighty-one cases of pneumoconiosis above stage one were detected by DR combined with DES,the detection rate of which was 79.41%;sixty-one cases of pneumoconiosis above stage one were detected by FSR,the detection rate of which was 59.80%;the detection rate of DR combined with DES for pneumoconiosis was higher than that of FSR(P<0.05).The detection rate of DR combined with DES for mediastinal lymphadenopath,pulmonary infection,emphysema and pleural thickening was higher than that of FSR(P<0.05 to P<0.01).At the same time,the small shadow distribution of the same stage pneumoconiosis detected by DR combined with DES was larger than that by FSR.Conclusions:DR combined with DES has better image quality and detection rate,which can be applied to the examination and diagnosis of pneumoconiosis.
