Diffusion-weighted imaging facilitates outcome predictions for post-cardiac arrest coma

Takeaway

  • An apparent diffusion coefficient (ADC) value of <650 x 10-6 mm2/s in >10% of brain tissue in an MRI obtained seven days after cardiac arrest is highly predictive for poor outcome in comatose individuals.

Why this matters

    Quantitative diffusion-weighted imaging (DWI) MRI analysis has several benefits as a diagnostic tool and may be used alongside additional biomarkers to predict outcomes in comatose individuals following cardiac arrest.
