Hi Xiaomin
it's really hard to say without seeing more detail in your images. Do you
have contrast in the temporal lobe? Frequently it goes away at 7T due to
dielectric effects. I'll cc Jon Polimeni who is our 7T (among other
things!) expert.
cheers

Hi Bruce,
I have done the recon-all (fs5.3) with the data collected from a 7T scanner
using MP2Rage. The recon went well without problem. But the the temporal
reconstruction looks clearly not correct (see attached). I tried to push
the pial surface outside by editing the white matter evidenced in the
attached figures, but has no effect to genera correct pial surface. I do
realize that the contrast is low in the anterior temporal lobes. However, I
am wondering if there are expert parameters I can use to push the pial
surface into the right place. If that isn't a option, can I use some other
images collected during the MP2rage scan to help the segmentation in the
anterior temporal lobe? Those extract scans are: inv1_nd, inv1_phs_nd, ,
t1, inv2_nd, invs_phas_nd,
thanks very much.
Xiaomin
