DTI Processing & Analysis with MedINRIA

Pierre Fillard¹, Nicolas Toussaint²

Although the MedINRIA software has been out for three years, it has never been formally presented to ISMRM. The objective of this work is to expose the rationale for the development of MedINRIA, a clinically oriented medical image processing software, and to present its DTI functionalities. We present the processing pipeline going from DICOM to fiber tracts. Notably, it comprises a unique anisotropic smoothing procedure enhancing the tensor quality of datasets of moderate SNR typical of clinical data. We further describe the interactive tract-of-interest selection tool and show an example of fiber bundle extraction and analysis with MedINRIA.
