Flash Signal Formula  \[  S \propto M_0\ \mathrm{e}^{-{TE}/{T_2^*}}\ \sin{\alpha}  \frac{1 - \mathrm{e}^{-{TR}/{T_1}}}{1 - \cos{\alpha}\ \mathrm{e}^{-{TR}/{T_1}}}  \] where:  \begin{itemize}  \item $S$: signal  \item $M_0$: proton density  \item $TE$: echo time  \item $TR$: repetition time  \item $\alpha$: flip angle  \item $T_1$: longitudinal relaxation time  \item $T_2^*$: effective transverse relaxation time  \end{itemize}
