Brief Summary:
The goal of this observational study is to determine whether specific advanced MRI measures are associated with functional outcomes in patients who are comatose after cardiac arrest The main questions it aims to answer are
Aim 1 Determine if stimulus-based functional MRI fMRI-measured activations are independently associated with favorable neurological outcomes after cardiac arrest
Aim 2 Determine if resting state functional MRI rs-fMRI-measured functional network connectivity is independently associated with favorable neurological outcomes after cardiac arrest
Aim 3 Determine if diffusion tensor imaging DTI-measured white matter integrity is associated with favorable neurological outcomes after cardiac arrest
Participants will undergo advanced MRI sequences at time of clinical MRI and will be followed for 6 months post-arrest

Detailed Description:
Our goal here is to determine whether advanced functional MRI and DTI sequences add actionable prognostic information relative to standard clinical MRI in patients who remain comatose after cardiac arrest We plan the following specific analyses
Aim 1 We will use logistic regression to measure the association between our primary outcome and fMRI BOLD response to a passive language stimuli b motor imagery or c passive sensory stimuli in a model with age Glasgow Coma Scale GCS score at time of MRI and presence of anoxic injury on clinical diffusion weighted MRI
Aim 2 We will use logistic regression to measure the association between our primary outcome and default mode network resting state functional connectivity in a model with age Glasgow Coma Scale GCS score at time of MRI and presence of anoxic injury on clinical diffusion weighted MRI
Aim 3 We will use logistic regression to measure the association between our primary outcome and diffusion tensor imaging DTI-measured mean white matter fractional anisotropy in a model with age Glasgow Coma Scale GCS score at time of MRI and presence of anoxic injury on clinical diffusion weighted MRI
