Assessment of myocardial injuries in ischemic and non-ischemic cardiomyopathies using magnetic resonance T1-rho mapping.

Myocardial T1ρ mapping appears to be reproducible and equally sensitive to acute and chronic myocardial injuries, whether of ischemic or non-ischemic origins. It may thus be a contrast-agent-free biomarker for gaining new and quantitative insight into myocardial structural disorders. These findings highlight the need for further studies through prospective and randomized trials.
