A Tractography Software Tool for Diffusion MRI Analysis


A tractography software

DSI Studio is a tractography software tool that maps brain connections and correlates findings with neuropsychological disorders. It is a collective implementation of several diffusion MRI methods, including diffusion tensor imaging (DTI), generalized q-sampling imaging (GQI), q-space diffeomorphic reconstruction (QSDR), diffusion MRI connectometry, and generalized deterministic fiber tracking.

Publications in Neuroscience


In the year of 2019 alone, DSI Studio has been used in more than 100 peer-reviewed publications. Research studies using DSI Studio have been published in top-tier journals including Nature Neuroscience, Nature Human Behavior, Nature Communication, Brain, Cerebral Cortex, and NeuroImage

More Than Just Pretty Pictures

The deterministic fiber tracking method in DSI Studio has achieved the highest 92% valid connection (ID#3) among 96 methods submitted from 20 different research groups, examined by an open competition (Nature communications, 8(1), 1349, 2017). The average accuracy is 54%.

Tumor Patients Benefited

Patient's story: 1, 2, 3
Fiber tracking in DSI Studio provides a superior presurgical evaluation of the fiber tracts for patients with complex brain lesions, including low grade and high-grade gliomas. Presurgical studies are built upon precise and accurate neuroanatomical knowledge, which allows doctors to reconstruct perilesional or intralesional fiber tracts, design the less invasive trajectory into the target lesion and apply more effectively intraoperative electrical mapping techniques for maximal and safe tumor resection in eloquent cortical and subcortical regions.
Our clinical experience applying DSI Studio fiber tracking has been reported in Neurosurgery, Journal of Neurosurgery, and Neuro-oncology among others. We are actively investigating its potential for not only presurgical planning and intraoperative navigation but also for neurostructural damage assessment, estimation of postsurgical neural pathways damage and recovery, and tracking of postsurgical changes and responses to rehabilitation therapy.
The latest innovation is the reconstruction of cranial nerves for presurgical evaluation in skull base surgery, with very promising results. The ultimate goal is to facilitate brain function preservation and recovery in patients undergoing complex brain surgery.


Histology Studies

DSI Studio can process high-resolution ex-vivo diffusion 'MRI microscopy' acquired at a large volume of imaging data, makes it possible to estimate the location, orientation, and anisotropy of the tracts in any histological specimens. This provides a powerful tool to investigate the structural topology of biological tissue to shade insight into its physiological function.

A brain parcellation map is required to generate the connectivity matrix. If you would like to use built-in atlas provided in DSI Studio to generate connectivity matrix, there is nothing you need to do after fiber tracking. You can open connectivity matrix dialog at [Tracts][Connectivity matrix]. DSI Studio will conduct a spatial normalization to ensure that the atlas is registered with the subject data. To check whether the linear transformation agrees well, you may open up the registration result using [View][Background registration].

If you would like to use your own parcellation map, and the map is in the MNI space, you may place the the map NIFTI file in the /atlas subfolder under DSI Studio package (In Mac, you may need to open the dsistudio.app package to see the folder). The ROIs will be included in the atlas database for you to calculate the connectivity matrix.

If your ROIs are in the native space, you can load the NIFTI file in the region list using [Regions][Open Region] (This steps should be done AFTER you have whole-brain fiber tracking done) and then check all ROIs using [Regions][Check all]. Once the ROIs are loaded in the region, you can bring up the connectivity windows by [Tracts][Connectivity matrix].
