For investigation of the underlying contrast mechanism, we varied the following sequence parameters using the averaged signal: (a) the slice angulation, (b) the off-resonance frequency of the saturation pulses, (c) the flip angle (FA) with saturation pulses, and (d) the flip angle (FA) without saturation pulses.\\ For (a), we found the angle dependency of the demagnetization field as shown in Figure~\ref{211018}A where $\varphi$ is the angle between the slice gradient and the main magnet field. The plot represents the fitted function $\vert(3\cdot cos^2\lbrack\varphi_{cor}\rbrack-1)\vert $ where $\varphi_{cor} $ takes additional gradients in read direction into account. Adjusted R$^2$ test of goodness-of-fit resulted in R$^2$=0.9958.
