A description of the successful implementation and
integration into clinical workflow of a
faster-than-acquisition sparse sampling reconstruction
is presented, with DCE perfusion imaging of the prostate
as an example application. A 4D time series with 55
timeframes is acquired with 2D SENSE acceleration in
under 6 minutes, with the reconstruction completing in
under 5 minutes; a reconstruction time of less than 5
seconds per 3D volume. Improved SNR and retained
sharpness are observed relative to a traditional SENSE
reconstruction of the same acquired data.
