[Mristudio-users] Mean_ADC units

[susumu]

The ADC value you are reporting seems too high. Please make sure that you
specify the correct b-value (in the first data input window) and the check
box of "consider b-value" in clicked (after you click "tensor calculation"
button).

If you didn't specify one of these, the calculation is based on b = 1. If
you use b=1,000, you have to divide the value by 1,000 to get the correct
unit (mm^2/s).

its unit is (mm^2/s) when you consider the b-value during the calculation.
