About this trial

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 question\[s\] 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.

Eligibility criteria

Qualifiers

survive of an in or out of hospital cardiac arrest

Disqualifiers

Drug overdose

Opinion of medical team patient unlikely to survive more than 24 hours (severe concurrent medical illness, dilated and unreactive pupils, etc..)

Following verbal commands (MD or RN note) once TTM is complete and normothermia is achieved (Day 2 or 3; Day of admission is Hospital Day 0). If no TTM is administered, this can be assessed on Hospital Day 2.

Following verbal commands (study team assessment) at time of MRI
