An
echo-planar spectroscopic imaging (EPSI) sequence has been demonstrated combining semi-adiabatic spatial-spectral pulses and echo-planar readout to facilitate fast magnetic resonance spectroscopic imaging (MRSI) at ultra-high field (7T)
Figure 1: Pulse sequence diagram of the EPSI sequence showing semi-adiabatic point-resolved spectroscopy (PRESS) sequence and bi-polar echo-planar readout.
Figure 4: Fully-reconstructed data showing spatially-resolved spectra with peaks of Creatine (Cr), Choline (Cho) and N-acetyl aspartate (NAA) visible and labeled in one spectrum. Horizontal axes are in parts-per-million (ppm) and vertical axes in arbitrary units representing signal amplitude.
