• * Age greater than 18 years
• * Have the ability to give written informed consent.
• * No tobacco use within the prior 6 months.
• * IPF (with a UIP or probable UIP pattern); or other forms of interstitial lung disease (ILD), including CTD-ILD, with a fibrotic component as noted by the presence of reticular markings and / or traction bronchiectasis and / or honeycombing on CT;
