Hi Ayaz
the big difference is that once you convert to analyze you will never be sure which side of the image is anatomically on the left and which is on the right, as analyze doesn't store this info.

Dear Bruce
If I use analyze would it effect the results?
Dicoms are preferable because?
I have processed about 30 subjects using analyze. I have noticed some cases where surfaces were not done correctly in few regions other than that no major problems.
If it makes big difference to use dicom. Should I use par images to transform them into dicom on scanner or is there any other way to do it?.
Thanks Ayaz

Hi Ayaz
you are *much* better off avoiding analyze as a format entirely. Can't you give the dicoms right off the scanner to recon-all?

Dear All,
I acquired the images using Phillips scanner. I converted the images from par into analyze using MRIcro. I noticed that images were flipped when I view them in the axial plane, i.e. when I look at the images on the computer screen the Right hemisphere (where we tapped the fish oil tablet) is on the right side of the image.
Should I flip the images before running through the recon-all?
Thanks
Ayaz
