This is detectable in the change of rate of magnetic relaxation, and measurable by T1 and T2 mapping using cardiovascular magnetic resonance (CMR). These markers provide novel quantifiable imaging measures for myocardial tissue characterisation. Despite similar principles, the measurements differ considerably between different sequences, vendors and field strengths, yielding a necessity to establish robust sequence-specific normal ranges, diagnostic accuracy, relationships with clinical characteristics, cardiovascular risk factors, routine cardiac imaging parameters, and prognosis. A further unknown relates to separation between healthy myocardium and subclinical disease in subgroups of patients with suspected cardiac involvement. Examples include patients with possible inflammation, such as in patients with a recent COVID-19 infection or vaccination.
