In this abstract we discuss application of PFG at long diffusion times and small q to discriminate between and hindered and restricted diffusion pools. We implement this as a preparation module to oscillating gradient diffusion weighted sequence. Since both the PFG and oscillating gradient waveforms are sensitive to diffusive motion, proper application of such PFG-filter requires that no cross terms exist between the two. Two sets of oscillating gradient diffusion weighted measurements on a celery stalk, one with the PFG-filter and other without. Our results confirm that in voxels containing heterogeneous regions, the PFG-filter can resolve the two compartments.
