Summary

This study looked at 60 adults with lung problems linked to vaping. Researchers used chest CT scans, ultrasound, and a procedure called bronchoalveolar lavage (BAL) to see how well these tests can diagnose vaping-related lung injury. The goal was to understand which tools work best to identify the condition and predict outcomes like hospital stay length and survival.
