The ky-t trajectories of (a) ‘top-up’ distortion correction using reversed phase encoding acquisition, (b) multi-echo EPI combined with parallel imaging for multi-contrast imaging, (c) EPSI for spectroscopic imaging, (d) PSF-EPI for distortion- and blurring-free imaging, and (e) the proposed EPTI using an efficient spatial and temporal CAIPI sampling trajectory for distortion- and blurring-free multi-contrast imaging, which is able to provide signal evolution information across EPI readout as shown in the bottom yellow and green boxes. Here, each dot represents an EPI readout line.
