In 84 patients with silicosis of various stages, a semi-quantitative topographical measurement of perfusion of the lung was performed with radionuclide albumin particles. At the same time, the scintigram of the lungs and x-ray films of the thorax were compared with each other. With increasing degree of severity of the silicosis, redistribution of the pulmonary blood flow was seen. The blood flow on the left side increases to the detriment of the right side until an approximate balance between the perfusion of both lungs is attained. With reference to the four quadrants, the greatest drop in perfusion occurs in the right upper quadrant, associated with the simultaneous greatest relative increase in the left upper quadrant. X-ray film of the thorax and scintigram pointed to a stronger and earlier silicosis affection of the right lung than of the left one.
对84例不同阶段矽肺患者，采用放射性核素白蛋白颗粒对肺部灌注进行半定量的局部测量。同时，将肺部闪烁图与胸部X光片进行相互比较。随着矽肺严重程度的增加，可见肺血流重新分布。左侧血流量增加，右侧血流量减少，直至两肺灌注达到近似平衡。参照四个象限，灌注下降最大的是右上象限，同时左上象限相对增加最大。胸部X光片和闪烁图显示，矽肺对右肺的影响比对左肺更强、更早。
