Native T1 mapping times are strongly influenced by elite athlete status
Authors' conclusion
Elite athletes have lower native T1 compared with non-athletes, both in women and men. Athlete- and sex-specific reference ranges should be applied when interpreting native T1 in athlete populations, especially in female athletes.
Study context
- Population
- Elite athletes (≥16 years; ≥10 h of exercise/week) and healthy non-athletic controls undergoing cardiovascular magnetic resonance imaging on a 1.5 tesla MRI machine
- Participants
- 240 vs 80
- Exposure
- Native T1 between elite athletes and healthy non-athletic controls
- Elite athletesn = 240
- Non-athlete healthy controlsn = 80
- Outcome
- Native T1
Methodological detailsage-matched
- Age-matched
Main finding
