Thanks for the advice, I did not know about the possibility of unchecking orientation and field of view options, that certainly helps. However, it does not solve my problem completely, because if I have to import a new DICOM series of an MRI performed after 6 months of follow up in a pre-existing dataset of a patient, it will keep replacing all the existing layouts.

I used to be enthusiastic of the CompareModule feature, but I had to stop using it because it permanently engulfed the working memory and processing units once used in a specific Slicer dataset, as described in this previous post ( [“Compare Volumes” module - display order - Support / Feature requests - 3D Slicer Community](https://discourse.slicer.org/t/compare-volumes-module-display-order/31261/6))
