Re: [Freesurfer] Methods for white matter hypointensities measure

Hi guys, We did some work on this topic that may be of interest to you. Basically we set up a K-Nearest-Neighbour classification system to automatically identify periventricular and deep WHMs. The algorithm is described in the paper. Wei Wen , Per

Hi guys, I am exactly in the same shoes (T1s and T2 FLAIRs), so could you please also keep me in the club? Many thanks, Martin On Thursday 13 May 2010 02:22:06 Laluz, Victor wrote: > Thank you for the prompt answer, as always Bruce!! > > I would be very interested in the techniques for multis

Re: [Freesurfer] Methods for white matter hypointensities measure

Thank you for the prompt answer, as always Bruce!! I would be very interested in the techniques for multispectral measurement of hyperintensities, as we have a pretty sizeable database of T1 images with corresponding T2 flairs for which we are very interested in accurate measures of white matte

Re: [Freesurfer] Methods for white matter hypointensities measure

Hi Victor we treat it as any other label - it's manually labeled in the training subjects and propagated into the aseg. Koen Van Leemput (ccd) has some tools for segmenting them from multi-spectral data that probably works better though (they aren't that well defined only on a T1). cheers Bruc

[Freesurfer] Methods for white matter hypointensities measure

Hello guys, I am curious as to how white matter hypointensities (on T1 mprage) are measured automatically for the aseg.stats file in FS? A group at UCSF is interested in using this measure for a study and would like to have a nice explanation or citation to describe how it is generated. I have
