肺结核（Pulmomaretuberculosis）为结核杆菌侵袭肺脏引起的一种炎症反应，其病变主要有渗出、增生和变质三个病理特征．由于X钱的成像需要穿透较厚的人体组织，故此X线胶片的影像本身较为模糊，在肺结核的增生和变质期，X线影像与局限性的肺部炎症、肿瘤，难以分辨，尤其是干 Pulmonary tuberculosis (Pulmomaretuberculosis) is an inflammatory reaction caused by Mycobacterium tuberculosis invading the lungs. The main pathological features are exudation, hyperplasia and degeneration. Since X-ray imaging needs to penetrate thicker human tissues, the radiographic image of the X-ray film itself is rather blurred. In the proliferative and cancerous stages of tuberculosis, X-ray imaging is associated with localized lung inflammation, tumors that are difficult to discern, and especially dry
