Rethinking white matter imaging

Diffusion MRI technology has changed tremendously; the SCIL (Sherbrooke Connectivity Imaging Lab), a world-renowned lab from where Imeka’s calling emerged, has been instrumental in reshaping white matter imaging technology.

The evolution of diffusion imaging

1990s :

DTI (diffusion tensor imaging)

1995s :

QBall Imaging

2000s :

HARDI (high angular resolution diffusion imaging)

Imeka’s cofounder, Maxime Descoteaux is a key player in the evolution of HARDI, q-ball imaging, spherical deconvolution and advanced tractography.

Our scientific background is the key to our ability to do much more than what is usually seen. Equipped with new, robust techniques, our team goes above and beyond.

For some, the term “DTI” is equivalent to the term “diffusion MRI”. This common misconception leads to a misunderstanding of DTI’s strengths and weaknesses.

Suboptimal use of diffusion MRI

Imeka understands the pitfalls of this useful technology and can help you avoid them. DTI is not robust to fiber crossings, which is in 66 to 90% of white matter voxels at the current imaging resolution. Imeka’s methods are robust to crossing fibres.

Does Imeka put DTI aside altogether?

Not at all. DTI measures are always computed and interpreted with care, using complementary free-water corrected measures and HARDI measures robust to crossing fibres.

Imeka uses HARDI as the basis for fiber tractography and fiber bundling.
