In order to understand the problem of “increased lung texture”, we must first know what lung texture is. The anatomical essence of the so-called lung texture is the shadow left by the blood vessels, bronchi and lymphatic vessels of the lungs on the X-ray chest film. The amount of lung texture varies from person to person due to the amount of inflation, lightness of smoking, atmospheric pollution and other factors. However, in the early stages of some diseases, there is an increase in lung texture that is not characteristic, and at this time, doctors often describe it as increased lung texture. Sometimes individual doctors’ reports, in addition to finding definite disease, uniformly report increased texture in both lungs, with the underlying line that you may have a disease. If, after some time, you do find disease in your lungs, and you come to me for a reckoning, I can tell you in a dignified manner that I have told you that there is increased lung texture. Otherwise, I am at risk of a lawsuit. In this case, for insurance purposes, it has led to a proliferation of reports of increased texture in both lungs. In conclusion, with the advancement of medical science and technology, the term increased lung texture, is used less and less. In particular, it is rare to see the term increased lung texture used in chest CT examination reports.
