External Email - Use Caution
I would like to ask for your advice regarding the use of NextBrain with MRI datasets acquired at different resolutions and coverage.
Specifically, I have: • A 3D T1-weighted image covering the whole brain with 1×1×1 mm voxel size • A second T1-weighted acquisition focused only on the brainstem, with higher resolution (0.5×0.5×0.5 mm)
Would it be possible (and methodologically sound) to combine these two datasets within the NextBrain pipeline? In particular, I am interested in whether the high-resolution brainstem scan can be integrated with the whole-brain image to improve segmentation or analysis in that region.
If this approach is feasible, I would appreciate any recommendations on preprocessing steps (e.g., registration, resampling, or intensity normalization) to ensure compatibility between the two images.
Thank you very much for your help.
