TR/TI combinations, residual tissue magnetization (MGM,t), control (MbC), and nulled (MbN) blood magnetization. The upper half of the table shows the values over a typical range of VASO TRs, whereas the lower half shows the values more closely centered on the range of capillary arrival times and measured in the methodological experiment.
