Subject motion is a known problem in MR spectral quality. This problem is even more severe in technique like J-difference editing, since it is based on the difference of two spectra. Using shot by shot acquisition with MEGA-PRESS approach for GABA editing and identifying motion-corrupted data utilizing water-signal based interleaved navigator scans, we have demonstrated a robust methodology for improved spectral quality control in J-difference editing. We have also demonstrated the possibility of recovering a measurement that otherwise would be corrupted by motion artifact.
