Which imaging studies are used for neuroprognostication after ROSC?

• A. Brain CT
• B. Brain MRI
• C. Brain CT and PET
• D. Brain CT and MRI

Answer: (D)

Neuroprognostication after ROSC relies on imaging to reveal the extent and pattern of brain injury that may influence recovery. A brain CT is typically the first step because it is fast and can quickly rule out life-threatening issues such as intracranial hemorrhage, mass effect, or large strokes that would change immediate management. However, CT isn’t as sensitive for early hypoxic-ischemic injury or for subtle, diffuse damage. A brain MRI, especially with diffusion-weighted imaging, is more sensitive in detecting hypoxic-ischemic injury and can show characteristic patterns that correlate with prognosis. MRI provides richer information about potential recovery by detailing where and how severely the brain has been affected. Combining CT and MRI leverages the strengths of both: rapid initial assessment with CT, followed by detailed prognostic information from MRI. PET is not routinely used for standard neuroprognostication in this setting due to practicality and availability, so the combination of CT and MRI best supports informed predictions after ROSC.
