WebIn regions in which Brownian movement of water molecules is constrained, DWI signal is increased (called restricted diffusion) owing to lack of net movement. However, because DWI sequences contain T2 weighting, areas within the brain with high inherent T2 signal intensity can also show increased signal on DWI sequence, so-called T2 shine-through.
