title: Improved partial k-space reconstruction technique for dynamic myocardial perfusion MRI.
abstract: The advent of partially parallel k-space data acquisition and reconstruction techniques has resulted in a drastic reduction in acquisition time. In this work, we have shown that the use of a new hybrid technique for reconstruction of partial k-space data can reduce acquisition time without loss of spatiotemporal resolution. The technique is termed hybrid k-t GRAPPA since it is a combination of k-t GRAPPA and an image-k-space keyhole technique. The hybrid method with an acceleration factor 4 generated better results than standard GRAPPA with acceleration factor 2 in preliminary results.
