External Email - Use Caution

Dear experts,

elaborating on the topics: As I read the samseg paper, I see that the flag --lesion wouldn't probably work well, since the imposed shape model, tuned for MS lesions, is not appropriate for perivascular spaces which have different shape. Is here a way for user to redefine the shape prior for samseg to tune it for perivascular spaces segmentation?

Thank you in advance for any help,

Antonin

Dear experts,We would like to quantify volume of brain perivascular spaces. Ideally longitudinally - i.e. to study the dynamics of perivascular spaces in multiple measurement of the same subject.

Is it possible to use samseg for this?

Do you think, that --lesion flag in samseg would work estimation of perivascular spaces? Or other setting of samseg will be better option?

Or, would you rather recommend other tools?

Any idea/comment will be greatly appreciated.

Regards,

Antonin Skoch
