摘要

Cardiac MRI (cMRI) is crucial for characterizing acute myocardial infarction (MI) complications. We present a case where acute ischemic edema demonstrated a magnitude (MAG) and phase-sensitive inversion recovery (PSIR) mismatch. This highlights that the MAG-PSIR mismatch can arise from the very long T1 times of acute edema, a key finding confirmed by T1 and T2 mapping [1].
