Fit results for in vitro and in vivo data. Shown are data, spectral and baseline fits and residual (a) conventional PRESS fit using in vitro data, (b) the first TE data from the multi-echo 2D model fit using in vitro data, (c) TE-averaged fit using in vitro data, (d) conventional PRESS fit using in vivo data, (e) the first TE data from the multi-echo 2D model fit using in vivo data, (f) TE-averaged fit using in vivo data.
