Figure 1From: Directions vs. averages: an in-vivo comparison for cardiac DTIMaps of helical angle (top row), fractional anisotropy (middle) and mean diffusivity (bottom row) for one example healthy subject. Maps were calculated for one reference data set (left hand column) with all available data and then with combinations of Ndirs and Nav to total Ntot=60 in each case. No consistent changes in parameter map were observed when altering Ndirs.Back to article page
