NCT ID NCT02888353
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether MRI scans are safe for people with pacemakers or implantable defibrillators, without the usual strict pre-screening. Researchers will scan up to 4,500 patients who need an MRI and check for device changes right after and weeks later. The goal is to see if current safety rules can be relaxed.
