\subsubsection{Signal Expression}  \[  S \propto V M_0\ \mathrm{e}^{-{T_E}/{T_2^*}}\ \sin{\alpha}  \frac{1 - \mathrm{e}^{-{T_R}/{T_1}}}{1 - \cos{\alpha}\ \mathrm{e}^{-{T_R}/{T_1}}}  \]  where:  \begin{itemize}  \item $S$: signal intensity  \item $V$: imaged volume  \item $M_0$: proton density  \item $T_E$: echo time  \item $T_R$: repetition time  \item $\alpha$: flip angle  \item $T_1$: longitudinal relaxation time  \item $T_2^*$: effective transverse relaxation time  \end{itemize}
