Blurred texture in both lungs generally indicates acute and chronic bronchitis with infection. The presence of blurred texture in both lungs on imaging requires the patient to be asked clinically whether he has cough, coughing, chest tightness, shortness of breath, and whether he has been smoking and exposed to dust for a long time, including masonry, coal mining, chef, hairdresser, tailor, etc. These jobs can easily lead to chronic infection in both lungs and form manifestations such as blurred texture in both lungs. If such manifestations occur, in addition to the diagnosis of chest X-ray, further examination by high-resolution CT of the chest can also be given to investigate whether other lung diseases such as pulmonary fibrosis and bronchiectasis are combined. Therefore, if there is blurred texture in both lungs without clinical manifestations and only imaging diagnosis, chronic bronchitis and acute bronchitis can be considered and no special treatment is needed. If accompanied by coughing and coughing sputum as well as blood tests suggesting an increase in total white blood cell count, it indicates the presence of respiratory tract infection, which can be treated with antibiotics.
