Comparisons of ex vivo diffusivities using the surface coil and the volume coil, and using one and four excitations. Most diffusivities in major brain structures differed when using different coils and numbers of excitations. AC, anterior commissure; AD, axial diffusivity; CC, corpus callosum; CT, cortex; EC, external capsule; HP, hippocampus; ICCP, internal capsule and cerebral peduncle; MD, mean diffusivity; ns, not significant; OT, optic tract; RD, radial diffusivity; ST, striatum; SC-1, surface coil and one excitation; SC-4, surface coil and four excitations; VC-1, volume coil and one excitation; VC-4, volume coil and four excitations. *p < 0.05; **p < 0.01; ***p < 0.001
