Fast phosphorus MR spectroscopic imaging of human brain using compressed sensing

This study aims at acquiring and reconstructing compressed sensing accelerated phosphorus MR spectroscopic imaging (³¹P-MRSI) of human brain in vivo. Accelerated ³¹P-MRSI volunteer data were acquired using pulse and acquire with compressed sensing at 3T. k-space data was randomly undersampled for a five fold scan time reduction while preserving the central portion, and reconstructed using three dimensional compressed sensing algorithm. This study showed that compressed sensing method could be applied for faster ³¹P MR spectroscopic imaging of human brain at 3T.
