Hello FSers,
quick question on the validity of FS automatic segmentation.
I have found longitudinal changes in hippocampus/amygdala volumes. Upon visual
inspection, there are some concerning issues, such as the labelling of CSF in
the amygdala. Mostly, these amount to a few clusters of between 5-20 voxels
around the boundaries of these structures in around 15-20 % of slices.
My question is do these errors sounds abnormally high (and don't think so,
having seen examples in some lit about FS accuracy), and are these errors
acceptable (publishable with a mild degree of confidence) in the context of a
longitudinal design, given the high test-retest reliability of FS segmentation?
Or are edits necessary?
I know there are probably no right/wrong answers on this, but any advice would
be greatly appreciated.
Best,
Garret
