Hello everyone.
I'm a Master student in the University of Barcelona and I am doing a work which is focused on Neuroimaging. For that work, I have to calculate the CBF but I have read the ASLtbx manual and have some doubts.
1. For CBF calculation is necessary a M0 image. In my case I only have one M0 image acquired and pASL images, so I don't know exactly how to get a M0i image (M0wm, M0csf) and what will be better for CBF calculation?
2. In ASLtbx GUI there is a parameter 'Label efficiency' which value is 0.95 by default. Is this a machine parameter?
Hope you can help me and thank you so much.
Daniel.
