计算机X线摄影在肺尘埃沉着症诊断中的应用研究

Application of computed radiography in the diagnosis of pneumosilicosis

目的探讨计算机X线摄影在肺尘埃沉着症诊断中的应用价值。方法将已确诊的101例肺尘埃沉着症患者和6例O+患者,采用CR高千伏和传统高千伏两种方法,各摄胸部正位片1张,由肺尘埃沉着症诊断小组,按照肺尘埃沉着症病诊断标准(GBZ70-2002)及23张标准片,随机对每张胸片质量和肺尘埃沉着症诊断及其分期进行评定。结果CR高千伏和传统高千伏胸片的一级片率分别为90.65%和46.73%,差异有显著统计学意义(P<0.01);对胸部肺内细微结构总体显示率分别为95.51%和59.07%,差异有显著统计学意义(P<0.01);对肺尘埃沉着症的检出率分别为97.20%和86.92%,差异有显著统计学意义(P<0.01)。结论在肺尘埃沉着症诊断中CR高于KV胸片,有望取代现行的传统高KV胸片。

Objective To evaluate the application value of computed radiography in the diagnosis of silicosis. Methods The chest of the confirmed diagnosis of 101 cases of silicosis and 6 objects of observation were radiographed by the CR high thousand vohageand and the tradition high thousand voltage. Refereing to Diagnostic Criteria of Pnemoconioses and 23 chest standard films, we evaluated every radiograph quality and divided the period of silicosis at random. Results The rates of advanced radiography chest CR high thousand voltageand and tradition radiograph of high thousand voltage were 90.65% and 46.73% , respevtively,the difference has statistical significance ,P 〈 0.01, the respective total manifestation rates of small construction of lung were 95.51% ,59.07% , the difference of total detection rates（97.20% and 86.92% ） had statistics significance;P 〈 0.01. Conclusion The CR high thousand voltage will substitute for the tradition high thousand voltage in the diagnosis of silicosis.
