Comparisons of ex vivo dimensionless diffusion tensor imaging (DTI) parameters using the surface coil and the volume coil, and using one and four excitations. Most dimensionless DTI parameters in major brain structures differed 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
