Hi Vitora,
the issue is not the orientation of the original image but rather the
spatial resolution. Usually, clinical sequences will have a slice
thickness of 3-4mm, which will result in a substantial partial volume
error when segmenting these images. As a rule of thumb, most clinical
sequences not acquired in one of the usual 3D sequences will yield
low-quality segmentation results for that reason alone. But in the end,
you may simply want to try a couple of datasets and see what the results
look like.
Cheers,
Marko
