Computer simulations for the optimization of the first inversion-recovery time (TI). A TI of 490 ms can approximately null the signals of the “normal” arterial wall, but the fibrotic tissue required a shorter TI time, i.e. 460 ms (a). As a trade-off, 480 ms was selected as the optimal delay time, providing a difference of 0.173 in normalized signals between the wall and IPH on the hyper T1-w contrast (b cross hair).
