![]() ![]() However, when using the J-difference editing technique 1H MEGA-PRESS, misalignment between mean edited ( ON ‾) and non-edited ( OFF ‾) spectra that may remain even after correction of the corresponding individual single-shot scans results in subtraction artefacts compromising reliable GABA quantitation. ![]() Phase and frequency corrections of magnetic resonance spectroscopic data are of major importance to obtain reliable and unambiguous metabolite estimates as validated in recent research for single-shot scans with the same spectral fingerprint. ![]()
