DTI-TK helps to reveal longitudinal white matter changes in FTD

garyhuizhang@stage.nitrcce.org (Gary Hui Zhang) — Wed, 05 Nov 2014 22:15:46 GMT

A new study from UCL Dementia Research Centre used DTI-TK, in particular its unbiased longitudinal processing pipeline, to reveal longitudinal white matter changes in frontotemporal dementia. The study appeared in one of the top neurological journals: Annals of Neurology:

DTI-TK recommended for tract-based spatial statistics (TBSS)

garyhuizhang@stage.nitrcce.org (Gary Hui Zhang) — Wed, 13 Aug 2014 10:10:00 GMT

A recent NeuroImage article entitled "Methodological considerations on tract-based spatial statistics (TBSS)" recommends the use of DTI-TK to improve the popular tract-based spatial statistics (TBSS) analysis pipeline. An online tutorial is available for users interested in integrating DTI-TK into the TBSS pipeline.

DTI-TK officially listed as a FSL plugin

garyhuizhang@stage.nitrcce.org (Gary Hui Zhang) — Fri, 22 Feb 2013 18:12:16 GMT

Dear all,

Pleased to announce that DTI-TK is now officially listed as a FSL plugin. Through the two-way interoperability support provided by DTI-TK, FSL users can continue to take advantage of the powerful tract-based spatial statistics (TBSS) framework with the additional benefit of the state-of-the-art tensor-based DTI registration powered by DTI-TK.

Introducing a longitudinal DTI analysis pipeline with DTI-TK

garyhuizhang@stage.nitrcce.org (Gary Hui Zhang) — Tue, 05 Feb 2013 16:41:15 GMT

Dear all,

I'm extremely excited to report that DTI-TK now delivers a major new application area:

Unbiased longitudinal DTI analysis.

This new framework is the first to apply our state-of-the-art tensor-based registration to accurately quantify longitudinal changes of tissue microstructure as assessed by DTI.

The framework is reported in our Neuroimage paper (in press):

http://dx.doi.org/10.1016/j.neuroimage.2013.01.044

Our evaluation demonstrates its superior specificity and sensitivity, which can be particular important for detecting early changes in many neurological disorders, such as dementia.

Standardized vs Study-Specific DTI templates

garyhuizhang@stage.nitrcce.org (Gary Hui Zhang) — Sun, 07 Oct 2012 14:09:21 GMT

Recent research has generally advocated the use of study-specific templates, for spatial normalization, over standardized ones. The standardized template, although not always as accurate as one's own study-specific template, does offer substantial benefit in computational efficiency, as the latter will require an expensive iterative bootstrapping construction. So a useful question to ask here is whether there are circumstances the standardized template may offer a satisfactory alternative to study-specific ones. This is precisely what Shengwei Zhang and Konstantinos Arfanakis, from Illinois Institute of Technology, have investigated in their recent article "Role of standardized and study-specific human brain diffusion tensor templates in inter-subject spatial normalization" in Journal of Magnetic Resonance Imaging.

DTI-TK used to understand young children with autism

garyhuizhang@stage.nitrcce.org (Gary Hui Zhang) — Sat, 01 Sep 2012 12:47:43 GMT

A recent paper to appear in the prestigious journal of Biological Psychiatry examines young children with autism with diffusion tensor imaging. The paper is led by Lindsay Walker from Dr. Carlo Pierpaoli's group at NIH. The authors used DTI-TK for spatial normalization of diffusion tensor imaging data.

DTI-TK used to detect WM changes before onset of psychosis

garyhuizhang@stage.nitrcce.org (Gary Hui Zhang) — Fri, 06 Apr 2012 21:16:59 GMT

A team from the Institute of Psychiatry, King's College London, used DTI-TK to help their investigation into pre-symptomatic brain changes in patients with psychosis. Their paper entitled "Alterations in White Matter Evident Before the Onset of Psychosis" is to appear in the prestigious journal of Schizophrenia Bulletin.
