Increased lung markings

Lung texture is mainly a special term in the radiology department. It mainly refers to the radiating strips from the hilum of the lung. The graded and shallow lung texture is mainly composed of some images of the pulmonary artery and pulmonary vein. The main feature of lung texture is that some coarse phenomena will appear in the process of the disease. The edges are relatively clear. If there are some other symptoms, the increase of texture is mainly seen from the chest imaging examination, and some radiating strip shadows can be seen.

Increased lung texture can be pathological or physiological. Generally speaking, the clinical value of increased lung texture is not great. It requires correct analysis and combination with other clinical conditions. The theory is more important, so the lung texture must be correctly classified and then better treatment can be carried out.

1. Increased vascular lung markings: The lung markings are coarse, and the blood vessels are maintained from the hilum to the lungs, often accompanied by an enlarged heart, which is mainly seen in rheumatic heart disease, congenital heart disease, etc.

2. Increased lymphocytic lung markings: The lung markings appear as fine reticular patterns in both lungs, which are commonly seen in pneumoconiosis, carcinomatous lymphangitis, etc.

3. Increased lung markings due to smoking: Increased lung markings in both lungs, but normal movement, mainly due to carbon monoxide deposition caused by long-term smoking.

4. Physiological increase in lung markings: mainly seen in the elderly and obese people. The former is due to the fact that the lung interstitium of the elderly is relatively abundant, which makes it more obvious on chest X-rays.

The latter is due to the obese physique of the examinee and the increase of subcutaneous fat, which leads to increased X-ray absorption, thus causing the illusion of increased lung texture on the chest X-ray.

The above are the common causes and main classifications of increased lung texture, which are mainly divided into common vascular and lymphatic, smoking and some physiological causes of increased lung texture. The main causes of increased lung texture are common phenomena, which are generally of little clinical value and require correct analysis and combination with other clinical conditions of increased texture, which is more important in theory. Therefore, the lung texture must be correctly classified and then better treatment can be carried out.
