摘　　要：目的探讨高千伏摄影联合数字X线摄影(digital radiography,DR)诊断尘肺病的应用价值。方法回顾性分析2023年1—10月泰安市公共卫生医疗中心收治的80例尘肺患者的影像学资料,其均行高千伏摄影、DR检查,判定2种检查单一检查和联合检查对疾病的诊断结果,对比不同检查方式的X线胸片质量、检查摄片平均时间、肺区小阴影分布情况。结果高千伏摄影联合DR检查的尘肺病阳性率为100%,高于单一高千伏摄影的62.50%及DR检查的90.00%(P<0.05)。DR检查的1级胸片率为93.75%,高于高千伏摄影的72.50%;且检查平均摄片时间为(6.97±1.26)min,短于高千伏摄影检查的(14.26±4.35)min(P<0.05)。DR检查对小阴影在肺区分布显示情况更优于高千伏摄影检查(P<0.05)。结论在尘肺病诊断中应用DR可取得较好的胸片图像质量,准确检出小阴影密集度,联合高千伏摄影,可以准确诊断并分期尘肺病,降低误诊和漏诊风险。Objective To explore the application value of high kV photography combined with digital radiography(DR)in the diagnosis of pneumoconiosis.Methods Retrospective analysis of imaging data of 80 patients with pneumoconiosis admitted to Tai′an Public Health Medical Center from January to October 2023,all of whom underwent high kV photography and DR examination.The diagnostic results of the two examinations,single examination and combined examination were determined.The quality of chest X-rays,average time of examination,and distribution of small shadows in the lung area were compared under different examination methods.Results The positive rate of pneumoconiosis detected by high kV photography combined with DR examination was 100%,which was higher than that of single high kV photography(62.50%)and DR examination(90.00%)(P<0.05).The first level chest X-ray rate of DR examination was 93.75%,higher than 72.50%of high kV photography,and the average imaging time was(6.97±1.26)minutes,which was shorter than(14.26±4.35)minutes of high kV photography examination(P<0.05).DR examination showed better display of small shadows in the lung area compared to high kV photography examination(P<0.05).Conclusion The application of DR in the diagnosis of pneumoconiosis can achieve good chest X-ray image quality,accurately detect small shadow density,and combined with high kV photography,accurately diagnose and stage pneumoconiosis,reducing the risk of misdiagnosis and missed diagnosis.
