T1 Relaxation Time and Relaxavity
Through measuring the Longitudinal Relaxation Time by inversion recovery pulse sequence(IR) to obtain the recovery time(т) and corresponding amplitude value M(т) of the original data. Then fitting t-M(т) curve with sigle-index model M(т)=М(0)(1-2е(-t/T1)) to obtain the Longitudinal Relaxation Time.
T1 Weighted MRI
T1 weighted image repressed the long relaxation signal and heighten the short relaxation signal, so the shorter the relaxation time is the lighter(deeper of red) the spots are in the picture(color map).
