(영어/영문/English) 1. T2 Decay (T2 relaxation, Transverse relaxation, Spin-Spin relaxation) MR signal decreases due to interaction between spins The RF pulse causes the magnetization (or spin) arranged in the vertical axis (Z) alongside the external magnetic field to lie in the horizontal (X-Y) plane. At this time, the phase of the spins is in-phase. Over time, in-phase spins are dispersed in the t..
