T1 MOLLI/T1 Look-Locker correction (magnitude images) | S(t) = |A (1 − B exp(−t/T1*))|; T1 = T1* (B − 1) | n/a |
T1 MOLLI/T1 Look-Locker correction (PSIR images) | S(t) = A (1 − B exp(−t/T1*)); T1 = T1* (B − 1) | n/a |
T2 spin echo (multi-echo and single-echo) | S(t) = A exp(−t/T2) + B; B > 0 | S(t) = A exp(−t/T2) |
T2-prepared balanced SSFP | S(t) = A exp(−t/T2) + B; B > 0 | S(t) = A exp(−t/T2) |
