Illustration of different time dimensions for MT-MACS, namely, cardiac pulsation, respiration and T2-prepared inversion recovery dimensions. For phase-resolved imaging, MT-MACS divides cardiac motion and respiratory movement into 14 and 6 bins, respectively. Within each inversion recovery period, MT-MACS contains 300 readout segments which can generate 300 various contrast weightings. 3 typical contrast weightings (i.e. bright-blood [BB], dark-blood [DB] and gray-blood [GB]) are picked out for multi-contrast assessment.
