I often see the conclusion that “the texture of both lungs has increased and thickened, please combine with the clinical” in the report of chest X-ray examination. What does this mean?
To understand the true meaning of such reports, we must first start with the composition of lung texture. The human lung is like a tree hanging upside down. The alveoli are the lush leaves, and the pulmonary artery, pulmonary vein, bronchi, and lymphatic structure in the lung are equivalent to branches. They are shown on X-ray images from the hilum to the lung field. The radially distributed dendritic shadows are medically called “lung texture”.
So, under what circumstances will the lung texture increase and thicken?
Under normal circumstances, young adults with strong blood gas, those after strenuous exercise, long-term smokers, pregnant women and other people will have increased lung texture and thickening.
Under pathological conditions, such as fever, early pneumonia, long-term cough, acute and chronic bronchitis, certain heart diseases or late heart disease (pulmonary congestion, pulmonary congestion, pulmonary edema, cardiac insufficiency, etc.), lymphatic diseases, occupational diseases Diseases, etc. will also show increased lung texture and thickening.
Certain equipment factors, such as photos or images obtained under different equipment conditions, will produce different effects of lung texture performance; the same patient will also produce different effects of lung texture performance under different equipment conditions. For example, the effects of ordinary photography and digital photography are quite different. The latter can display lung texture and structure due to its high resolution; in subjective judgment, different radiologists have different judgment standards for their experience, level, and experience.
Therefore, the significance of increased lung texture does not have an objective and quantifiable standard. It is related to the examinee’s own health status, equipment factors, and the personal experience of the diagnosing doctor. There are many reasons for the increase in lung texture, which can be pathological, physiological or technical.
Generally speaking, reports of increased lung texture in isolation are of little value for clinical reference. Only by carefully analyzing the nature of the increased lung texture and combining it with other X-ray manifestations, clinical conditions and technical conditions, can we draw correct conclusions.
