Healthy hearts measured: new baseline for MRI scans
NCT ID NCT01712581
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to find normal values for heart tissue measurements using MRI in 175 healthy volunteers aged 18-69. By establishing these baselines, doctors can better detect abnormalities like scarring or iron buildup in future patients. No treatment or intervention was given—only observation and measurement.
