Purpose  Spatio‐temporal encoding (SPEN) experiments can deliver single‐scan MR images without folding complications and with robustness to chemical shift and susceptibility artifacts. Further resolution improvements are shown to arise by relying on multiple receivers, to interpolate the sampled data along the low‐bandwidth dimension. The ensuing multiple‐sensor interpolation is akin to recently introduced SPEN interleaving procedures, albeit without requiring multiple shots.    Methods  By casting SPEN's spatial rasterization in  k‐ space, it becomes evident that local  k‐ data interpolations enabled by multiple receivers are akin to real‐space interleaving of SPEN images. The practical implementation of such a resolution‐enhancing procedure becomes similar to those normally used in simultaneous acquisition of spatial harmonics or sensitivity encoding, yet relaxing these methods’ fold‐over constraints.    Results  Experiments validating the theoretical expectations were carried out on phantoms and human volunteers on a 3T scanner. The experiments showed the expected resolution enhancement, at no cost to the sequence's complexity. With the addition of multibanding and stimulated echo procedures, 48‐slice full‐brain coverage could be recorded free from distortions at submillimeter resolution, in 3 s.    Conclusions  Super‐resolved SPEN with SENSE (SUSPENSE) achieves the goals of multishot SPEN interleaving delivering single‐shot submillimeter in‐plane resolutions in scanners equipped with suitable multiple sensors.
