T2 time

The time it takes for neighboring, radiofrequency-stimulated protons to relax relative to other protons in tissue (rather than relative to the magnetization provided by a magnetic resonance imaging (MRI) device). The T2 time varies from tissue to tissue. This is exploited in MRI to help generate contrast between adjacent tissues, e.g., between the white matter and grey matter of the brain, or between tissues with high fat content as opposed to those with high water content. Synonym: spin-spin relaxation time; transverse relaxation time

We assessed differences in the patient hemodynamics, oxygen metabolism data, and hepatic function and perfusion among T0, T1, and T2 time points by one-way analysis of variance, followed by Bonferroni corrections for multiple comparisons.
4) It increases the effectiveness of MR imaging by reducing the T1 and T2 times for tissues it is in contact with.
20] As the mobility decreases, the T2 time will decrease.
