Dear FreeSurfer Support Team,
I hope this message finds you well.
I am currently working with FreeSurfer and I have encountered a situation that I would like your guidance on. Specifically, I have noticed that FreeSurfer outputs the lateral ventricle in two parts, namely "Left-Lateral-Ventricle" and "Left-Inf-Lat-Vent." However, from an anatomical perspective, I am interested in obtaining the results for the four parts of the lateral ventricle separately: the anterior horn, central part, posterior horn, and inferior horn.
I understand that the "Left-Inf-Lat-Vent" might correspond to the inferior horn. Is FreeSurfer capable of providing the segmentation for the lateral ventricle in these specific sub-regions? If not, could you recommend any method or workaround that would allow me to obtain these detailed segmentations?
Additionally, if it is not possible to directly obtain these sub-regional volumes, is there a way to derive the ventricle volumes within each lobe (e.g., frontal, parietal, occipital, temporal) using FreeSurfer or any other tool?
Your assistance in this matter would be greatly appreciated. Thank you for your time and support.
Best regards,
Necati Emre Sahin.
