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 co-founder, Maxime Descoteaux was a key player in the evolution of QBALL and HARDI.

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.

Making light of DTI and diffusion MRI. 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

While many claim to provide diffusion MRI, most use dated technology without truly understanding the best practices surrounding methodology and analysis. Imeka understands the pitfalls of this useful technology and can help you avoid them. DTI is not robust enough to show fiber crossings, which research has shown, manifests in 66 to 90% of white matter voxels. Imeka’s current method, called HARDI, offers much better resolution and precision.

Does Imeka put DTI aside altogether?

Not at all. When a situation calls for DTI, our team is the best resource to obtain the basic diffusion metrics that DTI provides. DTI is actually at the basis of free – water imaging.

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