Interstitial Diseases Radiology

Interstitial diseases refer to a group of lung conditions that affect the tissue and space around the air sacs (alveoli) in the lungs. On chest X-rays or CT scans, these diseases can appear as abnormal patterns, often described as "reticular" or "nodular." These changes might indicate inflammation, scarring, or fluid accumulation in the lung interstitium, which can result from various causes, including infections, autoimmune diseases, or prolonged exposure to harmful substances. Proper imaging helps doctors assess the severity and potential causes of these lung issues, guiding further diagnosis and treatment.
