yes to the T1. The PD units are arbitrary and includes other things like T2*.

Hi,

What exactly is contained in the outputs of mri_ms_fitparms? Specifically: the T1 volume looks like it might have T1 times in ms -- is this correct? And I assume that PD is proton density -- is there a specific unit attached to these voxel values as well?

Thanks, Christian
