What findings on routine monitoring PFTs prompt you to pursue HRCT in your patients with SARDs?

That’s an excellent question, and the strategy might vary somewhat by the specific SARD, but in general, in any SARD patient undergoing annual PFTs, the presence of any of these should prompt an HRCT to evaluate for the development of ILD.

• FVC drop ≥ 10%
• DLCO drop ≥ 15%
• Moderate decline in FVC (5-9...

I don't think there is a way to set specific recommendations for this. Declines in physiology without other explanation, with or without symptoms, prompt me to get imaging. This is taking into consideration other things that affect the FVC and DLCO, but any significant decline (5% or greater?) would...
