^aCNR_contrast for a specific contrast is calculated by $\sqrt{2}\mathit{\text{mean}}(S_{\mathit{\text{contrast}}})/\mathit{\text{std}}(S_{\mathit{\text{contrast}},1}-S_{\mathit{\text{contrast}},2})$, where S_contrast,1 and S_contrast,2 are the signal intensity of two contrast maps acquired consecutively.

^b${\text{CNR efficiency}}_{\text{contrast}}={\text{CNR}}_{\text{contrast}}/\sqrt{\mathit{\text{scan time}}}$
