  • *One included study compared four T2-weighted MRI sequences.

  • †One included study applied two T1-weighted late gadolinium enhancement MRI interpretation methods.

  • ACUTE, acquisition for cardiac unified T2 oedema; FLASH, fast low angle shot; FSE, fast spin echo; FWHM, full width at half maximum; IR, inversion recovery; PSIR, phase-sensitive inversion recovery; SPGR, spoiled gradient echo; SSFP, steady-state free precession; STEMI, ST-segment elevation myocardial infarction; STIR, short-tau inversion recovery; TSE, turbo spin echo.
