Fig. 3. Typical attenuation plot of the NMR peak amplitude as a function of the diffusion-weighting factor b in the axial (open squares) and radial (filled squares) directions in P. argus muscle. This example is from a measurement of arginine phosphate diffusion at a diffusion time of 150ms. A steeper attenuation slope is indicative of a higher D, as seen for axial diffusion.
