Parameter Optimization for Quantitative Signal-Concentration Mapping Using Spoiled Gradient Echo MRI
Figure 1
Calculated values versus Gd-DTPA concentration for several experimental runs, labeled by the run number in our original database. The individual runs, rather than the averaged values, are shown to stress that the curves follow the same pattern of decreasing with increasing gadolinium concentrations in a fairly smooth form. Values of are obtained from a least squares fit of (1) (Section 2).
