Screening for rheumatoid arthritis-associated interstitial lung disease using lung ultrasound: a systematic review and quality appraisal of recent studies

Lung ultrasound is effective versus high-resolution computer tomography for screening rheumatoid arthritis–associated interstitial lung disease, with multiple diagnostic and severity scores tested across recent studies.

• Why it matters: Rheumatoid arthritis–associated ILD can strongly worsen patient outcomes, yet HRCT is the diagnostic gold standard, motivating less burdensome screening approaches.
• What they did: A systematic review of literature from the past 10 years identified 10 articles comparing lung ultrasound with HRCT for ILD screening in RA, including evaluation of diagnostic and severity scoring systems.
• The result: The reviewed evidence indicates lung ultrasound can serve as a screening tool comparable to HRCT in RA, and it supports future work on long-term follow-up and protocol standardization.
