[Mristudio-users] tensor calculation

[Castaneda, Salvador]

Hello Mri studio users,
 
I am working with a MRI scanner with bruker hardware and siemens
software. I acquire mosaic files and have been able to work with the
mosaic in DTI studio to then do a AIR registration. I produce whatever
maps i need. It works great. I then, upload the maps created by DTI
studio to another imaging software called PMOD, as Analize files, for
coregistration with a T2W rat brain Anatomy image. I am able produce
good quality ROIs of the brain areas i need. Just recently i have
discovered, that the MR can also provide for me the FA, TRACE, DWI, and
ADC maps as DICOMs. These I can also upload to Pmod for coregistration
with the anatomy. So theoretically I can choose to do this, but i have
noticed that the quality of the maps produced by the MR software are
somehow "lacking". So my question is : Is the AIR and mutual image
registration in DTI studio crutial for the processing of the data from
the MR? I like the images produced by DTI studio better, but what is the
basis of the improvement? how is it different to the images calculated
by the MR? The MR software is Siemens Syngo. I know that DTI studio also
provides tractography which makes a better tool for this analisis, but
if i would be just interested inthe FA maps, are the images produced by
the scanner enough? (regarding affine coregistration)
thanks in advance for your responses.
