Introduction


A diffusion MRI analysis tool 
DSI Studio is an open-source diffusion MRI analysis tool that maps brain connections and correlates findings with neuropsychological disorders. It is a collective implementation of several methods, including DTI, QBI, DSI, generalized q-sampling imaging, q-space diffeomorphic reconstruction, diffusion MRI connectometry, and generalized deterministic fiber tracking. 




Performance
The deterministic fiber tracking method in DSI Studio has achieved the highest 92% valid connection examined by an open competition (see Maier-Hein, et.al. (2017). Nature communications8(1), 1349, and the valid connection achieved by ID:03 at http://www.tractometer.org/ismrm_2015_challenge/resultsamong 96 methods submitted from 20 different research groups around the world.

Open source, open file format
DSI Studio is open source. The file format used in DSI Studio can be loaded/save from MATLAB, giving users the greatest flexibility to process the data. DSI Studio supports DICOM file format, Bruker 2dseq, and 4D NIFTI. It was designed to work with other popular tools such as FSL, TrackVis.
