Résumé
En une décennie, l’imagerie par résonance magnétique fonctionnelle (IRMf) s’est imposée comme un complément déterminant dans l’exploration clinique préchirurgicale de nombreuses pathologies. La principale application clinique de l’IRMf est la cartographie des régions fonctionnelles motrices et du langage, en particulier, avant un traitement chirurgical en neuro-oncologie. L’IRMf permet également d’étudier la perfusion et l’oxygénation cérébrale sous l’action d’agents vasomoteurs. Ces informations offrent une imagerie non invasive de la réactivité cérébrovasculaire dont les résultats prometteurs en neuro-oncologie sont en cours d’évaluation.
Abstract
Over the last decade, functional magnetic resonance imaging (fMRI) has become a useful, complementary tool in the presurgical evaluation of numerous brain diseases. In clinical practice, fMRI is commonly used to map eloquent sensorimotor and speech-related areas before surgical resection of brain tumours. fMRI also provides insights into brain perfusion and oxygenation changes in response to vasomotor agents. An evaluation of cerebrovascular reactivity is in progress.
