对早期矽肺患者，因矽结节较细小或不甚密集，一般胸片上往往不易显示，且与交叉之肺纹理或血管断面难以鉴别。采用局部放大摄影，则可使细小之结节通过放大而清晰显示。对于肺纹理交错处及血管之所面，亦可一目了然。当常规陶片可疑为矽结节簇时，经过放大照片多能进一步肯定? Early silicosis patients, due to the smaller or nodular silicon nodules, the general chest is often not easy to show, and with the intersection of lung texture or vascular cross-section difficult to identify. Using local magnification photography, you can make small nodules by zooming and clearly displayed. For the intersection of the lungs and the vascular surface of the place, but also at a glance. When the conventional suspicious pieces of silicon nodules, after zooming photos can be more sure?
