Bright-blood and dark-blood LGE images of a subject with thin subendocardial infarction. Panel a: Conventional bright-blood phase sensitive inversion recovery (PSIR) LGE images of the short-axis at mid-ventricular level (SA), two-chamber view (2CH), three-chamber view (3CH), and four-chamber view (4CH), which show a possible subendocardial infarction in the LAD territory. The transmurality of the scar is not well defined. Panel b: Dark-blood PSIR LGE images of the same views reveal a 25% subendocardial myocardial infarction (blue arrows) in the septal segments and 25–50% transmurality in the apical lateral wall. Furthermore, the short-axis dark-blood LGE image shows enhancement of the anterolateral papillary muscle (orange arrow), which was not observed using conventional bright-blood LGE. In this case, conventional LGE and dark-blood LGE were performed at 20 min and 10 min post-injection, respectively. For specific scan details, see ‘Philips Ingenia’ at Table 1
