Michael & Experts,
I have followed the BASIL tutorial for my ASL data (see parameters below) and have a perfusion image (in the native space directory) and was wondering about the values in each voxel. The tutorial states that these values are in the same (arbitrary) units as the original data. Unfortunately we do not have a calibration image to convert to physiological units. The range for these values is 0 to 30. Since I do not have a calibration image how do you recommend I present these values? Do I need to take it a step further?
Bolus duration (--bolus) would be 0.7
Inversion time (--tis) would probably be 2.5
BAT = 1.3
Cheers,
R
