pulmonary interstitial fibrosis

Pulmonary interstitial fibrosis occurs in the lung interstitium, refers to the existence of fine capillaries and some lymphatic channels between the alveoli and alveoli, also known as scar changes. CT is the most important diagnostic means. In addition, its imaging will show more specific manifestations, including grid-like changes at the base of the lung and near the pleura. If the patient has a non-specific cough, mainly dry cough, it indicates the possibility of pulmonary interstitial fibrosis and requires timely treatment.
