The measured diffusion rates as a function of the evolution time. The MAGSTE and bPGSTE measurements were shown in filled squares and circles, respectively. For the reference phantom, the measurements from both sequences were identical. However, for the glass beads phantoms, bPGSTE measurements were significantly lower than those measured using MAGSTE technique, especially at short evolution intervals. On the other hand, the bPGSTE and MAGSTE measurements became equal at long evolution time as a result of restricted diffusion and dominating diffusion attenuation during the evolution intervals.
