WebMay 14, 2024 · A T2WI relies upon the transverse relaxation (also known as "spin-spin" relaxation) of the net magnetization vector (NMV). T2 weighting tends to require long TE and TR times. after an RF excitation pulse, there is relaxation of the spins from the transverse plane toward the main longitudinal magnetic vector (B 0) - this is T1 weighting. WebJul 26, 2014 · The SFI has a problem partially due to the SLEDAI, where an organ-specific flare can become much worse and not be considered a more severe flare. For instance, … readlibs.com review
