The length of the net magnetisation vector for a spin echo sequence is given by the following equation: M t = M max (1-e -t/T1) Where M t is the magnetisation at time = t, the time after the 90 o pulse, M max is the maximum magnetisation at full recovery.

WebMay 2, 2024 · The rapid motion results in the T1 and T2 being about the same in pure water. In solutions of macromolecules and tissues the relaxation rate is much faster, i.e., the T2 time is shorter. This is related in part to the slower motion of protons both in macromolecules as well as water molecules attracted to the surface of the macromolecule.
