摘　　要：目的探讨DR高仟伏成像和胸部CT成像在尘肺病诊断中的差异。方法采用随机数字表法选取2013年6月至2019年12月在合肥市第三人民医院(合肥市职业病防治院)住院的40例尘肺病患者的影像学资料,比较DR高仟伏成像和胸部CT成像对尘肺病患者及其合并症检出率的差异,并评价两种方法在尘肺病分期中的价值。结果DR高仟伏成像和胸部CT成像对尘肺病检出的一致性较好(Kappa=0.648,P<0.001)。DR高仟伏成像对Ⅰ、Ⅱ、Ⅲ期尘肺病患者的检出率分别为73.1%(19/26)、87.5%(7/8)和100.0%(6/6),而CT成像的检出率分别为92.3%(24/26)、100.0%(8/8)和100.0%(6/6)。对于Ⅰ期尘肺者,CT的检出率明显高于DR高仟伏胸片成像(P=0.003)。CT成像对尘肺病患者肺大泡、胸膜增厚及纵隔淋巴结肿大等合并症的检出率均高于DR高仟伏成像(χ^2肺大泡=4.501,P肺大泡=0.034,χ^2胸膜增厚=6.275,P胸膜增厚=0.012,χ^2淋巴结肿大=4.507,P淋巴结肿大=0.034)。结论胸部DR高仟伏成像和CT成像对尘肺病的检出率一致,但胸部CT检查更易早期发现尘肺病患者的影像学改变及肺部合并症。Objective To explore the difference between DR high KV chest radiograph and chest CT in the diagnosis of pneumoconiosis. Methods The imaging data of 40 patients with pneumoconiosis who were diagnosed and treated inHefei Third People’s Hospital(Hefei Occupational Disease Prevention and Treatment Hospital) from June 2013 to Dec2019 were selected by random number table method to compare the difference in detection rate of pneumoconiosisand its complications between DR high KV chest radiograph and chest CT imaging, and to evaluate the value of the two methods in the staging of pneumoconiosis.Results The overall level of pneumoconiosis detected by DR high KV chest radiographand chest CT imaging was relatively consistent(kappa=0.648, P<0.001).The detection rate of Dr high KV imaging in patients with stage Ⅰ, Ⅱ and Ⅲ pneumoconiosis was 73.1%(19/26), 87.5%(7/8) and 100.0%(6/6), respectively, while that of CT imaging was92.3%(24/26), 100.0%(8/8) and 100.0%(6/6), respectively.For stage Ⅰ pneumoconiosis, the detection rate of CT imaging was significantly higher than that of DR high KV chestradiograph(P= 0.003).The detection rate of CT for pneumoconiosis patients with pulmonary bullae, pleural thickeningand mediastinal lymph node enlargement was higher than that of DR high KV chest radiograph(χpulmonary bullae2=4.501, Ppulmonary bullae=0.034;χpleural thickening2=6.275, Ppleural thickening =0.012;χlymph node2=4.507, Plymph node=0.034).Conclusion DR high KV chest radiographand chest CT have a high detection rate of pneumoconiosis, but it is easier to use chest CT examination to find the early pneumoconiosis imaging changes and pulmonary complications.
