Figure 1

Representative native T1 maps and LGE images from a patient with prior STEMI (infarct age = 18.5 years) and NSTEMI (infarct age = 25.6 years) are shown. Significant T1 elevations could be observed within the infarcted regions detected on LGE images (arrows). Good visual agreement was observed between the two techniques in terms of the location and spatial extent of the infarct. Median native T1 of the infarct was significantly elevated in both STEMI and NSTEMI patients. Percentage change in LGE signal intensity and infarct-to-remote CNR was significantly in LGE images were significantly higher than that of T1 maps.
