Images of bony densities on routine chest radiographs may simulate intrathoracic disease processes. Such entities include images produced by normal anatomic structures, anatomic variants, and benign processes. Most commonly, chest disease was simulated by virtue of projection or poor visualization of the bony density in question on the routine chest radiograph. The true nature of the "abnormal" images produced was usually revealed by further roentgenographic evaluation using specialized radiographic technics or additional views.
常规胸部X线片上的骨质密度影像可能会模拟胸内疾病过程。这些情况包括由正常解剖结构、解剖变异和良性病变产生的影像。最常见的是，胸部疾病是由于常规胸部X线片上相关骨质密度的投影或显示不佳而被模拟出来的。通过使用专门的放射技术或增加投照角度进行进一步的X线评估，通常可以揭示所产生“异常”影像的真实性质。
