Aim: to investigate if radial GRAPPA could be used to: (a) improve velic motion visualisation when compared with standard protocols and reconstructions; (b) enable multislice imaging by sufficiently accelerating real-time MRI data acquisition.
Methods: datasets of healthy adult volunteers were acquired at 3T and reconstructed using through-time and hybrid GRAPPA methods.
Results: velic motion visualisation was superior in GRAPPA images than in images acquired using standard protocols and reconstructions. Multislice imaging (two slices) at 8fps per slice was achieved.
Conclusions: radial GRAPPA shows promise as a method for use in clinical imaging of speech.
