WebTransverse magnetization decay is described by an exponential curve, characterized by the time constant T2. After time T2, transverse magnetization has lost 63 % of its original value. T2 is tissue-specific and is always shorter than T1. Transverse relaxation is faster than longitudinal relaxation. T2 values are unrelated to field strength. WebAs molecular motion slows (as in proteins and dense solids), T2 shortens and T1 again increases. T1 and T2 as a function of molecular size and tumbling rate. The minimum …
