As the heart occupies only a small fraction of the
chest, it is inefficient to support a FOV that covers
the whole chest. We developed an outer-volume suppressed
single-shot spiral perfusion sequence to achieve whole
heart coverage with high spatial and temporal resolution
with a FOV that only included the heart. We demonstrate
the successful application of reduced FOV single-shot
perfusion imaging which improves sampling efficiently,
and reduces residual aliasing artifacts resulting in
high quality perfusion images with very high temporal
(8ms) and spatial (2mm) resolution.
