It goes on to say otherwise unremarkable. That is the case with my hubby. Rest. As motion, and therefore the local field fluctuations, decreases below the Larmor frequency in tissues and tendons,dipoles that are aligned with the main magnetic field start contributing to T2 relaxation by causing local variations in precession rate. For example, deep white matter hyperintensites are 2.5 to 3 times more likely to occur in bipolar disorder and major depressive disorder than control subjects.
