尘肺的临床诊断,历来依赖X线摄片。随着对尘肺的研究深入,其诊断方法也在不断更新,目前在我国正逐步研究应用的是尘肺的磁化诊断,简称为肺磁图。现据有关文献作一简要的介绍。一,肺磁图的原理: 磁场的产生,根据电学原理,是由于电流或由于磁石而形成。人体内的生物电流可产生磁场,因职业而吸入在 Clinical diagnosis of pneumoconiosis, has always been dependent on X-ray. With the further research on pneumoconiosis, its diagnostic methods are constantly updated, now in our country is gradually applied to the diagnosis of pneumoconiosis, referred to as lung magnetic map. According to the relevant literature for a brief introduction. First, the principle of pulmonary magnetic map: the magnetic field generated, according to the electrical principle, is due to the current or due to the formation of magnets. The bioelectric current in the human body can generate a magnetic field, inhaled due to occupation
