Dear fsl users,
I'm trying to find information regarding the assumptions that should be
fulfilled for a valid siena/sienax analysis.
One factor that can affect the validity of the results is the imaging
acquisition characteristics [that has been mentioned in literature (Smith et
al 2002) such as different slice thickness among subjects, different
scanners, different sequences especially in case of Sienax which seems to be
more vulnerable].
What other issues besides the previous mentioned image characteristics can
affect the validity of the results (In which cases, even if all the
intermediate steps during the analysis seem to work ok, the results cannot
be considered valid?).
For example noisy images, distorted images ,or even physiological factors
(hydrocephalus patients etc)
Where can i find this information?
Thank you
