The
ERETIC method is a promising avenue of research for absolute concentration
quantification by MRS. However, in its initial form, this technique cannot be
implemented on most clinical MR scanners. We propose a new strategy, which
consists in transmitting the ERETIC signal before the localized spectroscopy
acquisition. This approach was evaluated on phantoms and on volunteers. The
results were compared to those obtained using the water signal as reference.
A very good correlation between the values obtained using the two methods was
observed. Moreover, the ERETIC method overcomes many of the drawbacks of the
other absolute quantification methods.
