Spectral-spatial excitation can be used for rapid time
resolved 3D acquisitions; however, maintaining adequate
spatial and temporal resolution is limited by the
required field-of-view coverage. Here, we demonstrate a
slice blipped EPI compressed sensing acquisition
strategy for accelerated 3D time resolved imaging of
[1-13C]pyruvate and lactate across a large
field-of-view. Image reconstructions of both
retrospectively and prospectively 2X undersampled in
vivo data is presented. Close agreement is shown between
fully and undersampled lactate to pyruvate area under
curve ratio.
