From: Single-quantum sodium MRI at 3 T for separation of mono- and bi-T2 sodium signals

Simulated separation of the mono- and bi-T2 sodium signals. (A) Extra-high SNR = 100. (B) High SNR = 50. (C) Regular SNR = 25. The SD (error bar) of the separated mmo (top) and mbi (bottom) consistently decreases with SNR increasing from 25 to 100, with an underestimate (arrow) for mmo or mbi near maximum value 1.0 but an overestimate (arrow) near minimum value 0.0. The amount decreases with SNR increasing.
