现时矽肺诊断中规定,以职业史及X线胸部平片摄影作为诊断的主要依据。近年来,随着现场粉尘浓度下降,肺部典型纤维结节型病变减少而多以间质纤维化病变为主,而1963年制订的矽肺诊断标准未重视肺部不规则阴影这一病变特点,因而给X线胸片诊断带来了困难,以致客观上出现大量可疑矽肺病人;加之X线胸片反映肺部病变比较迟钝,有人做过实验以矽结节病变组织贴于健康人胸壁,在厚度达到0.7厘米时才能见到胸片上阴影,所以在矽肺诊断时X线诊断与病理报告脱节的现象并不鲜见。若以胸片改变来估价药物疗效则更无能为力。Schlipkoter等认为矽肺病人的临床疗效观察过程中,在1-2年的时间内难以凭X线检查看出或确诊病变是否好转。因此,国内外学者都试图从
At present, the provision of silicosis diagnosis is based on occupational history and radiographs of chest radiographs as the main basis for diagnosis. In recent years, with the decrease of dust concentration in the field, typical pulmonary nodules lessening lesions and mostly interstitial fibrosis lesions, and the 1963 diagnostic criteria for silicosis did not pay attention to the irregular lung shadow of the lesion characteristics, Thus giving X-ray diagnosis of the chest has caused difficulties, resulting in a large number of objectively suspicious silicosis patients; combined with chest X-ray reflection of lung disease more sluggish, some people have done experiments with silicone nodular lesions attached to the chest wall of healthy people, in the Thickness of 0.7 cm to see the shadow on the chest X-ray, so in the diagnosis of silicosis X-ray diagnosis and pathological reports out of line is not uncommon. If you change the chest to assess the efficacy of the drug is even more helpless. Schlipkoter think the clinical efficacy of patients with silicosis during the observation, it is difficult within a year or two X-ray examination to see or confirm whether the disease is improved. Therefore, domestic and foreign scholars have tried from
