Long acquisition time due to the low sensitivity is one of the main constrains for using 31P MRSI on a regular basis. Different methods have been proposed to accelerate the acquisition showing advantages and limitations. In this work we present for the first time an in vivo experiment using flyback-Echo Planar Spectroscopic Imaging readout and compare it with the traditional fidCSI sequence. Results suggest that the technique might be suitable for clinical applications.
