We retrospectively applied 3D SPIRiT to the reconstruction of spatially and temporally-undersampled spiral Fourier velocity encoding (FVE) data, and compared this reconstruction with sum-of-squares, and with 2D image-domain SPIRiT without temporal acceleration. Using a single calibration step and 4-fold acceleration, 3D SPIRiT presented FVE time-velocity distributions with higher SER than the other approaches. This reconstruction is also twice as fast as the 2D image-domain SPIRiT reconstruction.
