Re: Fractional Anisotropy & Apparent Diffusion Coefficie
You can open ima files with basically any other software that has a "raw" import option. For ROI analysis you can try MNI Display, which is an ROI painting and analysis tool.

Can someone explain me how to use DTI interpolated tracking?
Can someone please explain me how to use the FACT method? My anisotropy maps look fairly good. I select a tracking section. I select a few "starting point" somewhere in corpus collosum - but the bundles generated are empty. What am I doing wrong. Am I supposed to "paint" the trac...

How can I make an RGM texture for anatomist?
For now it seems like that the tex files only allow you store an indexed texture value.
Is there a way where RGB fractions per nodes are stored and displayed directly?

Re: MRI segmentation
SPGR "inversion-recuperation" - Do you mean that you've used an MPRAGE kind of sequence - e.g. a low flip angle GRE sequence with an inversion recovery pulse in front? If so, your inversion pulse probably zeros out signal from CSF - thus making your 3D volume two compartmental - GM and WM,...

You should not worry too much Peter, with 10 averaging, you should get a pretty nice SNR... for these 6 directions. This should allow you to work. However, in the future I advice you to reduce the number of repetitions and increase the number of directions. This should reduce the risk of bias relat...

Siemense DTI data processing
Hey guys, I've collected some DTI data on a siemens TRIO and wondering if BV will be able to process them These are 6-directions data 2x2x3 mm and only 10 averages, so I'm concerned that SNR might not be sufficient. Has a siemense DTI import module been implemented already? I'd really like to give i...
