Bilateral lung texture disorder is a sign that radiologists find when examining the lungs on X-rays, that is, the lung texture appears to be unable to follow its own direction of travel, but is twisted, or turns or folds back, and most of the cases of this kind of situation are caused by inflammation. When X-ray examination, the lung texture is the image of the blood vessels accompanying the airway, because the airway is air, X-ray will pass through, so it is difficult to see the airway in the X-ray examination, but can see the blood vessels accompanying it. If the blood vessels are overly congested, edematous, or distorted, it is a sign that the airway is definitely inflamed, just like the skin is red and swollen when it is inflamed, and isn’t that redness a sign of congestion? The congestion of the lungs is manifested by textural disturbances, and these textures are the dilation of blood vessels and congestion. Lung texture disorder directly indicates that the airways are inflamed, and the inflammation is more serious, because in the early inflammation when the texture is just a little bit heavier, once there is a disorder of the surrounding swollen tissues around the airways have been distorted, and later will become a fuzzy shadow or even a patchy shadow, the gradual emergence of peribronchial inflammation.
