Lipomatous metaplasia in patients with myocardial infarction: evaluation with cardiac magnetic resonance

Introduction There has been few report on myocardial fat in MI using traditional MR techniques discriminating fat (i.e, T1WI with and without fat suppression), which probably attributes to reduced ability to characterize myocardial fat due to poor contrast of microscopic fat and partial-volume effects. Therefore somewhat sophisticated means such as multiecho Dixon method and IR-SSFP sequence were recently introduced to increase sensitivity of fat detection. We hypothesized that myocardial fat can be readily identified on cine imaging among generally used CMR sequences in which cancellation artifact occurs in borders of fat and water.
