[Freesurfer] Labels for comparison
Hello, I have successfully developed an automated algorithm combining pixel intensity-based and shape based approaches to segment the lateral ventricles. I have applied my algorithm to a small data set of 1.5 T1 ADNI images consisting of 24 AD (subjects with Alzheimer Disease) 19 MCI (subjects with Mild Cognitive Impairment) and 24 NEC (elderly controls). In my cases, particularly AD cases, I noticed that the segmentation of the lateral ventricles is connected to the third ventricle with foramina (usually 1 on a side or on both sides). Also, sometimes I find a connection with the posterior horn and third ventricle. I have researched CSF flow and from the literature, and all of these are real connections. I am near completion of developing an automated cropping scheme with a colleague to crop the third ventricle at these junctions. Our implementation is a combination of C++ code that we have developed and modified ITK classes. We have been viewing our segmented label maps in Slicer3 and generated 3D renderings using Slicer3's Model Maker module which is based on Marching Cubes. I have viewed a Freesurfer segmentation in Slicer3 based on a tutorial on the Slicer web site. I presented a poster of our results at the AIC and AAIC conference which I am at now in Vancouver, and a few people have asked me to compare my volumes with other methods. They were particularly interested in comparing my volumes with Freesurfer ventricle volumes and cross-sectional and longitudinal data. I was told and found csv files on the ADNI web site of Freesurfer analysis. I plan to correlate my values with Freesurfer's values, but I would be interested if Freesurfer also finds these connections between the third ventricle and lateral ventricles and also if it includes isolated temporal horn pieces when the horns are discontinuous due to the MRI not being able to resolve a very thin portion of the temporal horn. So, would it be possible, if I gave you a list of my ADNI subjects, for you to provide me the freesurfer label maps that correspond to the volumes in the csv files that are on the ADNI web site please? I could run Freesurfer but I would prefer having the label maps that exactly correspond to the Freesurfer ventricle volumes that are on the ADNI website. These would be from the two versions of Freesurfer noted on the ADNI web site in the ADNI Study Data/MRI image analysis link.

Re: [Freesurfer] Labels for comparison
Hi Bruce, I apologize for my detailist nature. I found the csv files on the ADNI web site containing the numerical values of volume in mm^3 numbers. Do you mean that there should also be the corresponding label maps on the ADNI web site, particularly of the third and lateral ventricles? I know when I ran recon-all it gave all the label maps of each parcellation of the brain and I could overlay these labels on the grey scale images and render 3D surface models in Slicer. If this is the case, could you confirm this. Then I'll email ADNI to see if they have the label maps corresponding to the csv files that they have in the ADNI Study Data -> MRI Images -> Image Analysis link. I am particularly interested in where Freesurfer separates the lateral ventricles from the third ventricle at the foramina, or at the connection between the posterior horns and the third ventricle. If you have any insight in this, that would be helpful. I am glad that Freesurfer includes the isolated horn pieces, as you explained. I particularly found that accurate segmentation of the horns was very important for the significance statistics in comparing AD, MCI and NEC groups. The next step for me will be sub-regional ventricle volumes, not only left and right but separate volumes of horns. I am curious how you defined the division of left from right for the ventricles? Was it special landmarks on the atlas? Thank you, John Sent from my iPhone 4S On 2012-07-17, at 2:13 PM, Bruce Fischl wrote: > Hi John > > have you checked with the ADNI folks?

[Freesurfer] question on invoking partial volume calculations in freesurfer 4.3
Hello, My freesurfer version is freesurfer-Linux-centos4_x86_64-stable-pub-v4.3.0 I noticed that the aparc+aseg.mgz label map is resampled to 1mm x 1mm x 1mm voxels, eventhough the .mgz grayscale mri image file remains as per the original voxel size and is not 1x1x1. mri_convert .nii to .mgz translates the grayscale image down the y direction in the horizontal plane transverse/axial slices. I noticed that the aseg.stats files list the number of voxels and the volume, and these numbers match because the voxel size is 1 x 1 x 1. My question is whether freesurfer 4.3 can be invoked to perform partial volume error corrections, and if so how do you invoke this feature? My interests lie in segmentations of the lateral ventricles including their posterior and inferior horns. thank you, john ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.

Re: [Freesurfer] question on invoking partial volume calculations in freesurfer 4.3
Thanks Doug. Do you know if the Freesurfer volumes in mm^3 that are posted on the ADNI website (particularly the longitudinal studies) include partial volume corrections? i.e., if they were run to include partial volume calculations?

Re: [Freesurfer] Re: zero determinant error in using mri_convert rawavg.mgz orig.mgz --conform
Hello Bruce and Nick, Thank you, Bruce, for the clarification that FreeSurfer when reading my dicom files, it thinks the slice thickness is 0, and thank you Nick for your help as well. Just for your information, 3D Slicer was able to read in the dicom files successfully. I find this perplexing. Anyways, I tried an alternate route with FreeSurfer which seemed to work reasonably well. The dicom files that I was using were derived from a nifti .nii file. So I used the original .nii file and everything worked with FreeSurfer, except when I tried to perform non-uniform intensity normalization (the program gave a segmentation crash) when I typed: mri_nu_correct.mni --i orig.mgz --o nu.mgz --n 2 So I did the talairach transformation without performing the non-uniform intensity normalization, and then I was able to calculate the total intercranial volume when I typed: talairach_avi --i orig.mgz --xfm transforms/talairach.auto.xfm cp transforms/talairach.auto.xfm transforms/talairach.xfm mri_segstats --subject subjid --etiv-only Now that I am able to calculate the total intercranial volume with FreeSurfer, I am interested in the details of the procedure that FreeSurfer uses to calculate the intercranial volume. Afterall, the pudding is in the details. I am interested in what components of the head FreeSurfer includes/excludes in its calculation of total intercranial volume. I am also interested in the details of the mathematical and computer algorithm used to calculate the total intercranial volume (as well as for calculating ventricle volume). I am performing image analysis for research on Alzheimer's Disease and I need to understand these calculations in detail. Can you recommend any good references that would provide me information on how FreeSurfer calculates the total intracranial volume and ventricle volume? Also, please let me know if the source code is available for my viewing if at all possible, which would be really handy.

[Freesurfer] source code for FreeSurfer and comparison with Neuroquant
Hello, I am reviewing the papers outlined in the "FreeSurfer Analysis Pipeline Overview". I would find it helpful if I could download the source code for FreeSurfer. Please let me know if this is at all possible. Also I was wondering how different Cortech's commercial sister program to FreeSurfer called Neuroquant is from FreeSurfer? Other than Neuroquant being able to be used clinically, I was wondering if the functionality is different.

Re: [Freesurfer] measuring cortical thickness using FreeSurfer
Hi Bruce and Pedro, Thank you both for sending me your suggestions. Just to let you know, because my .dcm (dicom) files had a space and two dots in the filenames: (e.g. "2008_12_08.ek -0035-0001-1.dcm" ) (and using quotes around the file name or "\ " within the filename without the quotes did not work with recon-all), recon-all truncated the filename before the space as "2008_12_08.ek" feeding it to an mri_convert command and gave an error message. So I worked around this problem as follows: I converted the .dcm series to a nifti .nii volume using 3D Slicer, and then used mri_convert to convert the .nii format to .mgz format. Then I ran recon-all on the .mgz formatted file and it is now running successfully. I see on the online tutorials and slides, that this process takes about 20 hours. Is there a way to only run partial steps pertaining only to the cortical thickness? Pedro also suggested that I go through the FreeSurferBeginnersGuide wiki which I am doing now. Also, reading some mailing lists emails, I noticed that matlab can be used to analyze the cortical thickness statistiics, and also freesurfer comes with matlab scripts. I will try these tools out as well.

Re: [Freesurfer] measuring cortical thickness using FreeSurfer
Hi Bruce, Okay, thank you. I understand and can see that to do an accurate job, the pipeline must be complicated. I have eight processors on my linux desktop computer. Maybe some parts of recon-all are multi-threaded which could speed things up for me :-) Thank you, John 2011/7/5 Bruce Fischl > sorry, but the majority of the time is required.
