“…In two larger studies, lower whole-brain median ADC and the percentage of brain volume with an ADC value below the threshold of 650-700 9 10 -6 mm 2 /s were significant predictors of poor outcome [63,64]. When using ADC depression as a prognosticator in patients who were cooled after CA, it is important to realize that hypothermia per se can cause ADC depression, as was demonstrated in a rat model and a patient study [65,66]. Therefore, MRI has to be reserved for the rewarming phase, and is ideally performed few days after the arrest.…”

The prognosis of patients who are admitted to the hospital after cardiac arrest often relies on neurological examination, which could be significantly influenced by the use of sedative drugs or the implementation of targeted temperature management. The need for early and accurate prognostication is crucial as up to 15-20% of patients could be considered as having a poor outcome and may undergo withdrawal of life-sustaining therapies while a complete neurological recovery is still possible. As current practice in Belgium is still based on a very early assessment of neurological function in these patients, the Belgian Society of Intensive Care Medicine created a multidisciplinary Task Force to provide an optimal approach for monitoring and refine prognosis of CA survivors. This Task Force underlined the importance to use a multimodal approach using several additional tools (e.g., electrophysiological tests, neuroimaging, biomarkers) and to refer cases with uncertain prognosis to specialized centers to better evaluate the extent of brain injury in these patients.

“…In brain areas vulnerable to global ischemia, the ADC reduction was time-dependent and differed between patients with good and poor outcomes. [20][21][22] However, no data describe how these patterns change when patients are treated with TH after cardiac arrest. Additionally, no data compare the prognostic value of DWI at different time points after cardiac arrest in the same patients.…”

Repeated diffusion weighted imaging in comatose cardiac arrest patients with therapeutic hypothermia

“…These authors found no correlation between initial MRI and outcome or ischemic lesions seen on subsequent 24‐ or 96‐hour MRIs. However, in this study 9 of the 10 patients had a good neurologic outcome, suggesting that this was an unusual cohort of out‐of‐hospital cardiac arrest patients 48 . This study used the apparent diffuse coefficient for evaluation of ischemia, whereas a subsequent study 49 of 19 out‐of‐hospital cardiac arrest patients evaluated high signal intensity in 21 brain regions on DW‐MRI at 6 hours after return of spontaneous circulation as a predictor of poor neurologic outcome.…”

“…Three studies have assessed MRI as a predictive tool when performed within 6 hours after return of spontaneous circulation and before initiation of targeted temperature management. The first study used MRI at 2 hours after return of spontaneous circulation to predict the outcomes of 10 witnessed out‐of‐hospital cardiac arrest patients 48 . These authors found no correlation between initial MRI and outcome or ischemic lesions seen on subsequent 24‐ or 96‐hour MRIs.…”

Neurologic prognostication after resuscitation from cardiac arrest

Out‐of‐hospital cardiac arrest remains a leading cause of mortality in the United States, and the majority of patients who die after achieving return of spontaneous circulation die from withdrawal of care due to a perceived poor neurologic prognosis. Unfortunately, withdrawal of care often occurs during the first day of admission and research suggests this early withdrawal of care may be premature and result in unnecessary deaths for patients who would have made a full neurologic recovery. In this review, we explore the evidence for neurologic prognostication in the emergency department for patients who achieve return of spontaneous circulation after an out‐of‐hospital cardiac arrest.
