Another possible cause of these white matter lesions could be Lyme disease. Almost immediately, they lose coherence as some spin slightly faster than the others. T2 relaxation, also known as spin-spin relaxation or transverse relaxation, refers to the progressive dephasing of spinning dipoles resulting in decay in the magnetization in the transverse plane (Mxy). The magnitude of the MR signal after an RF-pulse is in turn, dependent on two factors: T1 reflects the length of time it takes for regrowth of.
