Increased lung texture

Overview: Pulmonary texture refers to the radiating strip-shaped shadows extending from the hilum to the periphery of the lung field as seen on chest imaging. It is mainly composed of pulmonary arteries, pulmonary veins, bronchi and lymphatic vessels. The increase in lung texture on X-ray chest radiographs is mainly seen in the following cases: (1) Bronchial lung texture increases: the uneven thickness of the lung texture, which is often mixed with deformed texture and small honeycomb shadows, common in chronic bronchitis, bronchodilation Wait. (2) Increased vascular lung texture: The texture of the lung is large, and the characteristics of blood vessels running from the hilum to the lung are maintained. It is often accompanied by an enlarged heart. It is mainly seen in rheumatic heart disease and congenital heart disease. (3) Increased lymphatic lung texture: The lung texture appears as a slender network in both lungs, which is common in pneumoconiosis and cancerous lymphangiitis. (4) Smoking lung texture increase: showing increased lung texture, but normal walking, mainly due to carbon deposition caused by long-term smoking. (5) Increased physiological lung texture: mainly seen in the elderly and obese. The former is due to the relatively rich interstitial lungs of the elderly, which shows increased lung texture on X-ray chest radiographs; the latter is due to the obesity of the subject and the increase in subcutaneous fat, which results in increased X-ray absorption, resulting in increased lung texture on the chest radiograph Illusion.
