NCT ID NCT03253692
First seen Jan 05, 2026 · Last updated Apr 29, 2026 · Updated 13 times
Summary
This study tracked radiation doses from heart CT scans (CCTA) in 66 adults across multiple hospitals to see how much radiation is actually used and how well dose-reduction methods work. The goal was to understand variations between different machines and sites, and to find opportunities to lower radiation exposure without sacrificing image quality. No new treatment was tested; the focus was purely on measuring and improving safety of an existing diagnostic tool.
