What is pulmonary fibrosis? And how is it described from an X-ray? I was told I have hardening of the lung does this mean I have it?

Loose Term. Pulmonary fibrosis is a loose term used for numerous interstitial lung diseases. Most often though, it is used for idiopathic pulmonary fibrosis (ipf). X-ray will not be a good modality to evaluate ipf. A ct chest will be helpful.
Pulmonary fibrosis. Pulmonary fibrosis is a pattern seen on ct scanning of the lung. There are several things that can cause fibrosis such as smoking, exposure to asbestos, autoimmune diseases such as rheumatoid arthritis, and certain medicines. Some of these diseases can be treated while others are progressive and fatal. Fibrotic lung diseases cause a restrictive physiology that could be described as hardening.
