Spatial distribution of eigenvector variability was
investigated in the human calf at 3T using different
amoungs of signal averages and encoding directions. The
principal vector was found to vary much less than the
two minor vectors. Furthermore, the spatial distribution
appeared non-random and favourable to the peripheral
musles, although noisier for the minor eigenvectors. The
spatial distribution appeared dependent upon scan
acquisition conditions.
