Hello,
I am new to SPM, and I have downloaded SPM5b. I have some questions about
how to do the normalization and coregistration of my SPECT and MRI images. I
have a single SPECT image and its corresponding T2 MRI image.
1) Normalization: should I simply normalize the structural MRI image, and
then coregister it to the functional SPECT image (unnormalized)? Or should I
normalize both images and then coregister them? I am not sure what is
normally done here.
2) Segmentation: is it normal practice to segment the structural MRI image
and then coregister? Do I normalize the MRI first, segment, and then
coregister with the SPECT? Also, which segmented image do I use?
3) Image display: when I display my SPECT image, the top two boxes show a
squished up picture, but the axial direction looks okay. Do I just play
around with the resize x & y options? I attached a SPECT image to this email.
Thanks for your help!
Anita
