Indications et impact thérapeutique de l’imagerie par résonance magnétique en soins critiques

Abstract : Introduction: magnetic resonance imaging (MRI) has several recognized indications in critical care patients, but its therapeutic impact in this setting has never been explored. Objective: to evaluate the indications and therapeutic impact of MRI in critical care. Patients and methods: we conducted a two-center retrospective observational cohort study, including one center with neurocritical care activity, over a five-year period from 2016 to 2020. We included all patients aged 18 years or older who received an MRI during their critical care hospitalization. The primary outcome was the occurrence of a therapeutic impact, whether by therapeutic change or withdrawal of life-sustaining therapies (WLST), after MRI. Results: we included a total of 337 patients, with 370 MRIs analyzed. There was no therapeutic impact after MRI in 60% of cases, whereas the remainder was represented by a WLST in 28% of cases and a therapeutic modification in 12% of cases. Cardiac arrest was the most frequent disease, up to 26% of cases. Brain MRI accounted for 92% of cases. The exam was performed more often for diagnostic rather than prognostic purposes in the overall population. Conclusion: the majority of MRI in critical care does not lead to a therapeutic impact, raising the question of a more restrictive strategy.
