## Abstract __T__~1~ maps obtained with modified Look‐Locker inversion recovery (MOLLI) can be used to measure myocardial __T__~1~. We aimed to evaluate the potential of MOLLI __T__~1~ mapping for the assessment of acute and chronic myocardial infarction (MI). A total of 24 patients with a first MI

✦ Synopsis
Novel CMR techniques are needed to assess reversible myocardial injury in acute MI. Our results show that pre-contrast T1 mapping CMR could be such a technique: increasingly higher T1 values are associated with larger extent of acute myocardial injury and with reduced functional recovery at 6 months.

At a given field strength tissues present with specific T 1values. Reference values for normal unenhanced myocardium have been established. We hypothesize, that infarcted myocardial tissue can be delineated from normal myocardium by means of T 1 -maps in unenhanced and contrast-enhanced scans.
## Abstract ## Purpose To determine whether contrast between acutely infarcted and normal myocardia in T~1~‐rho‐weighted cine TFE (T~1ρ~‐TFE) and delayed‐enhancement (DE) images (measured using a metric percent enhancement (PE)) varied with the dose or time of imaging after contrast administration
## Abstract ## Background Quantitative relaxation time measurements by cardiovascular magnetic resonance (CMR) are of paramount importance in contrast-enhanced studies of experimental myocardial infarction. First, compared to qualitative measurements based on signal intensity changes, they are les
