Sorry, motion was my best guess.

Dear Anastasia,
The T1 images were acquired in a sagittal orientation, and the DTI images in
an axial orientation.
Does this help ?
Thanks

Hi Rotem - No problem. Were these scans by any chance acquired
with a coronal slice prescription? In the axial views that you
sent, the artifact that you're pointing to looks like
misalignment between consecutive coronal slices, which could be
due to head motion.

Dear Anastasia,
I tried several times to upload these images in a
non-compressed way, but
they were too big and my posts were rejected, with
no opportunity for any
other upload way.
Is there any other way for me to upload it so that
everyone can see it ?
Attached are the images in a non-compressed fashion.
I will be very happy if
u will have a look, and post your answer to me and
the list to save some
time, until I will be able to consider another way
to upload them.
I know that we should write to all the list, but at
the moment if the images
are not visible this won't help - so I will really
appreciate if u will have
a look but also tell me what is the best way to
upload them so that all list
members will be able to see them.
Thank u very much for your help.

Hi there,
Long time:). Well I wrote to the list
several times
regarding high FA values
I got when performing DTI analysis.
Today we know that the problem was an
additional
direction (we had 17
directions instead of 16 - we used a
Philips
scanner,1.5T). So we deleted
the additional slices and the high
values indeed
disappeared, but then
another problem came up (tried several
subjects so
the problem is not
specific to a subject) -
I noticed an artifact that I can't
explain - please
see the attached
pictures.
This artifact existed even before I
deleted the
additional slices, also - I
see the artifact also when loading the
masked
volume...It is cyclic - run
over all slices...
any ideas ?
I'm using version 5.2 and I know the
command lines
are correct (send it to u
in the past).
Thanks for your help
