Hi Ed,

ADC: apparent diffusion coefficients (ln(S0/S1)/(b1-b0))

RA: relative anisotropy (sqrt(var(lambda))/mean(lambda))

radialdiff: radial diffusivity (lambda2+lambda3)/2

IVC: inter-voxel correlation

where lambda = (lambda1, lambda2, lambda3) the eigenvalues S0 = signal intensity without the diffusion weighting S1 = signal with the gradient

Hi,

Is it possible to give the exact definition of the output of dt_recon, in particular:

• adc
• ra
• radialdiff
• ivc
