If the fine lung markings aren't visible, then the x-ray may fail to detect some diseases.

如果无法看到那些细小的纹理，X光可能会漏掉某些病灶。

The most common abnormal finding is " ground glass" opacities, meaning that some portions of the lungs look like a " hazy" shade of gray instead of being black with fine white lung markings for blood vessels.

最常见的胸片异常表现是磨玻璃影，意味着肺部某些部位有模糊的灰色阴影，而非呈现黑色背景下细小的白色肺纹理（即血管影）。
