MRXCAT myocardial perfusion reconstruction and quantification example. Fully sampled reference (a), 8x k-t PCA (b) and 8x k-t SPARSE (c) reconstruction results and error maps. A mid-ventricular slice at peak left-ventricular (LV) and myocardial enhancement and profile along the dashed red line for 32 time frames are shown. (d-f) Signal intensity-time curves for reference and reconstructed data from 4 voxels (inset). (g-i) Fermi MBF quantification of stress perfusion simulation in 8 slices with 6 angular sectors per slice (inset). Ground truth MBF was 3.5 ml/g/min. The gray values for all error maps were scaled from 0 to 80%.
