300,000 people get chest X-Rays in massive screening trial
NCT ID NCT07585214
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is checking if chest X-rays can reliably find lung, heart, and esophagus problems in 300,000 adults during routine check-ups. People getting a health exam will have a chest X-ray, and if something looks off, they'll get a more detailed scan to confirm. The goal is to see if this simple test is good enough for widespread screening to catch diseases early.
