Hi Feng

it's impossible to give a comprehensive answer to this type of question other than try it and see if it works. Too much depends on the exact placement and contrast properties of the lesions Bruce On Tue, 6 Oct 2015, chenhf_uestc wrote:

Hi, Bruce   Do you mean that if the tumor located in the subcortical area, there is not large impact to reconstruction; if the tumor located in the cortical regions, there will affect the cortex reconstruction?   Another question is that I have MRI data from stroke patients. However, there are different lesions in the brain across the patients, including cerebral cortex and subcortical area. How could I perform reconstruction analysis?   Best, Feng

Hi, freesurfer experts,       If my data came from the patients with brain tumors, could I perform   recon-all analyses to calculate cortical thickness, surface area and so o

If not, could I mask the brain region with tumor and then conduct such   analyses? I think the tumor might lead to the inaccuracy of cortical   reconstruction       Best,   Feng
