Figure 2.
Left: A comparison of ideal (thin line) and 3D localized (thick line) PRESS (TE=70 ms) simulations with experimental 3D PRESS-localized phantom spectra of Lac, NAA, Glu and mI. Right: Corresponding signal distribution in a slice from the 3D localized volume. The asterisk (*) denotes the spectral location (10 Hz wide) of the localized signal distribution. The spectral separation between coupled spins is indicated by δν for each metabolite.
