[Mristudio-users] DTI mapping using nifti files

[Nida Sajjad]

Hi,

I have data set of DTI images of patients in the form of nifti files. I want to use DTI mapping in DTI studio to calculate FA and MD of specific ROI after creating them. Can you tell me best way to convert my data to be useable in DTI mapping.

Thanks,
Regards,
Nida

Subject: [Mristudio-users] btable of Siemens Mosaic sample dataset

Hi, I believe that there are discrepancies with the sample Siemens Mosaic dataset. In the sample dataset, the gradient table is provided. The gradient table can of course also be read from the DICOM header. I performed the pipeline using both methods, and noticed that the results are different. I think that the b vectors are not the same, and also the bvalue suggested (700), is incorrect as a value of 800 is read from the DICOM header. 
Of course most people would obtain the btable from the header, so this is not a major issue, but I wanted to point it out in case someone uses the btable provided in the given text file.  Thanks, 

Deepa
