This study aims at assessing compressed sensing reconstruction for faster phosphorus MR spectroscopic imaging (31P MRSI) of human brain. A 31P MRSI dataset containing a tumor region and a healthy region was created based on the metabolite peak intensities of a volunteer dataset acquired at 3T. k-space data was randomly undersampled while preserving the cental portion for a reduction factor of 1.6, and reconstructed using compressed sensing. This study showed that compressed sensing reconstruction could be applied for faster 31P MR spectroscopic imaging, and its performance will be assessed in brain tumors.
