摘要
目的探讨数字X线成像系统(DR)胸片联合高频CT(HRCT)诊断职业性肺尘埃沉着病(尘肺病)的价值。方法回顾性选取2018年1月~2020年9月清远市慢性病防治医院诊断的45例职业性尘肺病患者作为研究对象,均施以DR胸片及HRCT检查。比较DR胸片、HRCT单独检查与联合检查的P影、小阴影、大阴影显示率,鉴别疾病分期、相关并发症的符合率,并比较DR胸片、HRCT单独检查的图像质量。结果DR胸片联合HRCT的P影显示率(80.00%)高于HRCT、DR胸片(60.00%、42.22%),差异有统计学意义(P<0.05)。DR胸片联合HRCT、HRCT小阴影显示率(22.22%、17.78%)高于DR胸片(2.22%),差异有统计学意义(P<0.05)。DR胸片联合HRCT、HRCT诊断肺尘病总符合率(100.00%、93.33%)高于DR胸片(71.11%),差异有统计学意义(P<0.05)。DR胸片联合HRCT鉴别Ⅰ期尘肺病符合率(57.78%)高于DR胸片(35.56%),差异有统计学意义(P<0.05)。DR胸片联合HRCT、HRCT鉴别肺气肿、胸膜增厚、气胸、肺大泡符合率高于DR胸片,差异有统计学意义(P<0.05)。HRCT成像质量高于DR胸片,差异有统计学意义(P<0.05)。结论在职业性尘肺病诊断中DR胸片与HRCT的联合应用,可提高P影显示率,提升疾病分期及并发症鉴别准确率。
Objective To explore the value of digital X-ray imaging system(DR)chest radiograph combined with high-frequency CT(HRCT)in the diagnosis of occupational pneumoconiosis.Methods A total of 45 patients with occupational pneumoconiosis diagnosed in Qingyuan Chronic Disease Prevention and Treatment Hospital from January 2018 to September 2020 were retrospectively selected as the research subjects,and all were examined by DR chest radiograph and HRCT.The display rates of P shadow,small shadow and large shadow,identification of disease stages,and the coincidence rate of related complications were compared by DR chest radiograph,HRCT examination alone and combined.The imaging quality was compared between DR chest radiograph and HRCT alone.Results The display rate of P shadow of DR chest radiograph combined with HRCT(80.00%)was higher than that of HRCT and DR chest radiograph(60.00%,42.22%),and the differences were statistically significant(P<0.05).The display rate of small shadow of DR chest radiograph combined with HRCT and HRCT(22.22%,17.78%)was higher than that of DR chest radiograph(2.22%),and the differences were statistically significant(P<0.05).The overall coincidence rate of DR chest radiograph combined with HRCT and HRCT in the diagnosis of pneumoconiosis(100.00%,93.33%)was higher than that of DR chest radiograph(71.11%),and the differences were statistically significant(P<0.05).The coincidence rate of DR chest radiograph combined with HRCT to differentiate stageⅠpneumoconiosis(57.78%)was higher than that of DR chest radiograph(35.56%),and the difference was statistically significant(P<0.05).The coincidence rates of DR chest radiograph combined with HRCT and HRCT in the identification of emphysema,pleural thickening,pneumothorax,and bullae were higher than those of DR chest radiograph,and the differences were statistically significant(P<0.05).The imaging quality of HRCT was higher than that of DR chest radiograph,the difference was statistically significant(P<0.05).Conclusion The combined application of DR chest radiograph and HRCT in the diagnosis of occupational pneumoconiosis can improve the display rate of P shadow and the accuracy of disease staging and complication identification.
