Segmented center-out echo planar spectroscopic imaging implements a k-t-space sampling that reduce the convolution of spatial and temporal encoding by privileging the concomitant acquisition of center k-space lines. Because of the considerable acceleration, a water reference scan can be measured in a few seconds along with a template scan for the realignment of forward and reflected ADC. Spectral Nyquist ghosts that may arise from the use of strong flyback rewinders can be effectively handled by implementing a sixteen step EXOR phase cycling and enables the detection of the J-coupled resonance of glutamate in 2.1 min.
