Comparison of compressed sensing reconstruction algorithms for 31P magnetic resonance spectroscopic imaging

Phosphorus MR spectroscopy and spectroscopic imaging (³¹P-MRS/MRSI) provide information about energy metabolism, membrane degradation and pH in vivo. In spite of their proven utility, ³¹P-MRS/MRSI are not often used primarily because of the challenges imposed by the low sensitivity and low concentration of metabolites leading to low signal to noise ratio (SNR), coarse spatial resolution and prolonged acquisition time. More recently there has …
