1. A computerized system for displaying images acquired by magnetic resonance (MR) imaging, said system comprising:

  • at least one computer processor coupled to associated memory, display and input/output ports and configured to;

    (a) acquire separate 3D multi-slice non-contrast reconstructed MR images of blood perfusion within left ventricle (LV) myocardium for each of plural inversion time (TI) intervals during a same cardiac phase;

    (b) perform segmentation of each of the 3D multi-slice non-contrast reconstructed MR images; and

    (c) display, to an operator of said system, separate LV slice reconstructed images of blood perfusion at each of plural slice positions from each of the 3D multi-slice non-contrast reconstructed MR images on which the segmentation has been performed, for each of said plural TI time intervals, in sequences of respectively corresponding LV slice reconstructed images of blood perfusion at each of said plural slice positions, as a function of the TI time intervals, simultaneously in a single display panel, in a color map format for each segment resulting from the segmentation.
