Performance comparison of different schemes using stress data of patient with myocardial infarction. Here, we show two time frames, image time profile (through a cross section in (A)), an averaged ROI perfusion curve, and parametric slope maps for the different schemes. The patient had reduced myocardial perfusion uptake in the inferior wall as depicted in the slope maps. This was later confirmed as infarction by LGE as shown in (E), where the infarct region is thinner compared to the normal myocardium. k-t SLR reconstructions depict these regions efficiently in comparison to STCR and k-t SPARSE/SENSE methods as seen in (A-D). Specifically, STCR and k-t SPARSE/SENSE show over-smoothing and motion blur respectively, while k-t SLR is robust to this as depicted by the red and green arrows in the spatial frames and the time profiles. The differences are reflected in the perfusion curves as well.
