This study aims to investigate the relative performances
of 2D iterative frame based and a 3D direct improve the
feasibility of 3D direct compressed sensing
reconstruction for faster phosphorus MR spectroscopic
imaging (31P MRSI) with comparing 2D iterative frame
based reconstruction. A 31P MR spectrum was acquired
from the frontoparietal lobe of a volunteer at 3T, and
two dimensional 31P MRSI datasets that included a tumor
region and a healthy region were created. k-space data
was randomly undersampled with two patterns while
preserving the central part for reduction factor of 4.26
for 16x16 and 3.71 for 32x32 arrays. This study showed
that 3D direct compressed sensing reconstruction works
better than 2D iterative frame based reconstruction.
