I noticed on my MRI results that it said There is a single punctate focus of T2 prolongation in the left corona radiata, nonspecific. Following a radiofrequency pulse, this form of relaxation occurs with the time constant T2, where T2 is the time it takes for the transverse magnetization vector to decay to 1/e or 37% of its initial magnitude. The result is that the Mxy component of the magnetic vector decreases exponentially as a function of the T2 time constant (Figure 1).
