Increased lung texture is an image descriptor of chest X-ray or CT examination report, which does not necessarily require treatment, and should be analyzed comprehensively according to the patient’s condition.
Lung texture is a dendritic shadow radiating outward from the pulmonary hilum, composed of pulmonary arteries, pulmonary veins, bronchioles, lymphatic vessels and a small amount of interstitial tissue.
Physiologically, the lung texture may increase and thicken in young and strong people, after strenuous exercise, long-term smokers, pregnant and pregnant women.
Under pathological conditions, such as early stage of pneumonia, acute and chronic bronchitis, chronic obstructive pulmonary disease, pulmonary edema, pulmonary stasis, cardiac insufficiency, lymphadenitis, pneumoconiosis and so on will show thickening and increase of lung texture.
In addition, the photographs or images obtained under different equipment conditions may produce different effects of lung texture; the same patient under different equipment conditions may also produce different effects of lung texture. Different radiologists’ experience, level, and experience, as well as different workplace reading conditions, and the advantages and disadvantages of monitors, may affect the judgment effect.
Generally speaking, the clinical significance of an increase in lung texture is not significant when the imaging report only suggests an increase in lung texture, and it is necessary to analyze it together with the clinical symptoms and signs in order to obtain a more accurate conclusion.
