On HRCT images, IPF is characterized by patchy, peripheral, subpleural, and bibasilar reticular opacities.

HRCT findings that are suggestive of alternate diagnoses include predominantly ground-glass opacities (nonspecific interstitial lung disease), cysts, lymph node enlargement (sarcoidosis), pleural plaques (consider asbestosis), dilated esophagus (consider connective tissue disorder), and distal clavicular erosions (consider rheumatoid arthritis).
