Hi Sooyun

what kind of acquisitons do you have? For just T1 we probably don't have anything. If you had a T2 or FLAIR we do have some tools, but they are not distributed/documented/tested/etc.... yet.

sorry Bruce

Hello, dear fellow Freesurfers.

I was wondering whether there was any way to automatically measure the longest or the maximum length(or thickness or diameter) of cortical lesions.

By this I mean that if there were to say 3 distinctive lesions in the brain of the patient, each with 1mm, 2mm, 7mm maximum diameters, the 7mm will be chosen as the representative "maximum lesion thickness" of the patient.

Considering that there are automated methods to measure the average cortical thickness, with a little tweaking, it seems plausible that we can measure the lesion's maximum thickness automatically too.

I know there are provided methods that able us to automatically segregate lesion specific areas from T1 FLAIR images. Will there be a way to get the measurements that I want using these masks?

Using the masks isn't essential as long as I can get the maximum lesion thickness automatically.

I'm not so familiar with computational algorithms so please any form of advice will be appreciated.

Thank you for taking your time to read this. Hope all of you have a great day.

Sincerely, Sooyun Cho.
