FIG. 7.
Comparison of Cramér-Rao lower bounds (CRLBs) of brain metabolites and fast-relaxing macromolecules (MM) between 4T and 7T as a function of the number of transients. Number of subjects and number of spectra per subject are the same as in Fig. 6. Error bars = SD. Horizontal lines represent the CRLB achieved with NT = 128 at 4T.
