Figure 6. mcDESPOT signal differences relative to appropriate noise levels.

Top: a reference mcDESPOT signal containing two bSSFP curves (using both alternating and non-alternating RF excitation phase every repetition) and one SPGR curve. Bottom: differences between the reference signal above and signals with very distinct parameter values. For example, f_F values vary between 15% and 28%. Nevertheless, the uncertainty due to noise is still very large compared to the signal differences, so one would expect difficulty in differentiating the signals.
