Query: Multiple-coil k-space interpolation enhances resolution in single-shot
  spatiotemporal MRI   Purpose: Spatio-temporal encoding (SPEN) experiments can deliver single-scan
MR images without folding complications and with robustness to chemical shift
and susceptibility artifacts. It is here shown that further resolution
improvements can 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
resolution-enhancing procedure becomes similar to those normally used in SMASH
or SENSE, 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 in the sequence's complexity. With
the addition of multibanding and stimulated echo procedures, 48-slices
full-brain coverage could be recorded free from distortions at sub-mm
resolution, in 3 sec.
  Conclusion: Super-resolved SPEN with SENSE (SUSPENSE) achieves the goals of
multi-shot SPEN interleaving within one single scan, delivering single-shot
sub-mm in-plane resolutions in scanners equipped with suitable multiple
sensors.
