Key Points
Rarely, middle-aged adults (>40 yr and <60 yr), especially those with risks for familial pulmonary fibrosis, may otherwise manifest the same clinical scenario as the typical patient older than 60 years.
The recommendations in this guideline are for the patterns and distributions of images obtained by high-resolution CT (HRCT) imaging and, thus, require that patients be subjected to HRCT of the chest for evaluation.
