Thanks @maylistran01 !
The PR LGTM !

@AliceJoubert It makes me realize that the snippet seems wrong by saying "Medical Resonance Imaging".

@maylistran01 do you think you can do it ? You need to change this file: https://github.com/aramis-lab/clinica/blob/dev/docs/snippets/abbreviations.md and replace "Medical" with "Magnetic", make a new commit and push it.
