RE: Corpus Callosum Segmentation Information?
Thank you very much for this very useful tool, I tested yuki2 on a few subjects and it did very well to delineate the CC and to compute the different areas of the CC. I wonder if there is a paper published (that could be cited) detailling the different steps of the technique used, or if there is data about the reliability of the delineation (or any kind of comparison with a manual delineation) ? Anyway, many thanks for this tremendous tool !
Best regards,

Samuel

Thanks for your comment.  These images were segmented using a new automated multi-atlas-based segmentation method.  We intend to include a description of the technique here in the future.  We also have an abstract accecpted on this in the ISMRM 2012 in Melbourne and plan to write a full paper about it.  The success rate of the algorithm depends on the quality of the images, ranging from 75-95% of cases.  In the remaining cases, minor manual touch-ups are required.  

By the way, the x1 factor in the speardsheets is subject's age and the x2 factor is the eTIV (as provided by OASIS) raised to the power of (2/3) in order to be used a covariate in the analysis of the area.  I will include a description of this as well in the near future.


Best,
Babak
