摘  要:目的为评价数字化摄影(directdigitalradiography,DR)胸片在石棉肺诊断上的可行性,对DR胸片和传统胶片一增感屏摄影(filmscreenradiography,FSR)胸片的石棉肺影像表现进行差异比较和一致性分析。方法以60例石棉肺患者为研究对象。同一天拍摄DR胸片和FSR胸片,比较两种胸片在石棉肺小阴影形态、密集度、胸膜病变和期别判定上的差异。结果60例研究对象胸片小阴影形态表现为s、t和P,以不规则小阴影s、t为主,FSR胸片小阴影为s或t影的占95.0%,DR胸片占91.7%。小阴影广泛分布在6个肺区,以中下肺表现明显。两种胸片对小阴影形态判定的构成比和在肺区中的分布比例的差异均无统计学意义(P〉0.05)。两种胸片对60例研究对象肺区密集度诊断的一致率为64.2%(231/360).K=0.62(95%CI:0.54.0.69)。两种胸片对43例小阴影形态判定完全一致的研究对象(258组肺区)密集度比较,两种胸片的一致率为81.0%(209/258),x=0.79(95%CI:0.72—0.87)。FSR胸片判定胸膜增厚10例(16.7%,10/60),与DR片12例(20.0%,12/60)相比,差异无统计学意义(P〉0.05)。FSR胸片判定I期石棉肺53例(88.3%,53/60),Ⅱ期7例(11.7%,7/60),DR片I期石棉肺5I例(85.0%,51/60),Ⅱ期9例(15.0%,9/60)。2种胸片诊断期别构成比比较,差异无统计学意义(P〉0.05)。FSR和DR胸片对60例研究对象尘肺期别的判定的一致率为93.3%(56/60),K=0.71(95%CI:0.45—0.98)。结论DR胸片在石棉肺小阴影分布、密集度判定和胸膜病变识别上与FSR相似。Objective To evaluate the feasibility of direct digital radiography (DDR) in the diagnosis of asbestosis, and to analyze the difference and similarity between DDR and film-screen radiography (FSR) in terms of the radiographic features of asbestosis. Methods A total of 60 cases of asbestosis underwent FSR and DDR of the chest in the same day. The FSR and DDR findings were compared with respect to shapes and profusion of small opacities, pleural abnormality, and diagnostic stages. Results The patients showed "s", "t", and "p" small opacities on chest images, with irregular "s" and "t" ones predominating (FSR: 95.0%; DDR: 91.7%). The small opacities were widely distributed in six lung zones, especially in middle and lower zones. The shapes and distribution of small opacities did not differ significantly between FSR and DDR findings (P〉0.05). For all the 60 cases, the two radiographies demonstrated a concordance rate of 64.2% (231/360) for the profusion of small opacities in lung zones (K=0.62, 95%C1: 0.54-0.69), and for the 43 cases (258 lung zones) who displayed identical small opacity shapes on the two radiographies, the concordance rate was 81.0% (209/ 258) (K=0.79, 95%CI: 0.72-0.87). FSR revealed 10 cases (16.7%) of pleural thickening, compared to 12 cases (20.0%) on DDR (/9〉0.05). FSR revealed 53 cases (88.3%) of stage I asbestosis and 7 cases (11.7%) of stage I1 asbestosis, compared to 51 cases (85.0%) and 9 cases (15.0%) on DDR (P〉0.05). There was no significant difference in diagnostic stages between the two radiographies (P〉05), demonstrating a concordance rate of 93.3% (56/60) (K=0.71, 95%CE 0.45-0.98). Conclusion DDR is similar to FSR in determining the shapes, distribution, and profusion of small opacities, pleural abnormality, and diagnostic stages.
