Authors' conclusion

We present a robust, observer-independent workflow for anatomically resolved quantification of ischemic injury in HIBI. Atlas-based segmentation integrated with voxel-intensity ADC analysis, enabled generation of granular data on the pattern and extent of ischemic brain injury following cardiac arrest.

Study context

Population
Post-cardiac arrest patients with hypoxic-ischemic brain injury (HIBI)
Participants
10 patients
Exposure
White matter vs Gray matter

Main finding

As reported in the abstract

Spatial distribution of ischemic injury
  • Spatially heterogeneous but consistently affected the putamen, thalamus, and posterior cortical regions (e.g., pericalcarine and perirolandic cortices)

Observational data: associations, not effects.

Further findings

Relative lesion volume (% of total brain volume) · greater involvement in white matter

P = 0.005

Relative lesion volume (% of total brain volume) — Overall mean relative lesion volume
28.4 ± 14.1%

Overlap of susceptibility-weighted imaging (SWI) and apparent diffusion coefficient (ADC) hypointensities

Overlap of SWI and ADC hypointensities
<1% of all voxels
  • indicating negligible confounding by intraparenchymal blood
