Nonspecific interstitial pneumonia (NSIP): multiple examples with typical imaging patterns 

I review multiple cases of NSIP on imaging and share clinical and diagnostic pearls for the radiologist and anyone else interested in thoracic imaging. NSIP is usually secondary rather than idiopathic and the most common underlying condition is connective tissue disease. This will be exemplified in this video. Some literature that is helpful in diagnosis will also be covered. Diffuse pulmonary ossification's significance in the setting of interstitial lung disease will also be discussed.
