Prognostic value of arterial spin-labeling perfusion in anoxic brain injury: A retrospective cohort study

Table 1 Statistically significant associations between arterial spin-labeling signal intensity, arterial spin-labeling-diffusion-weighted imaging correlation, and patient outcomes

Variable/region	Finding	P value
Right occipital lobe	↑ ASL in late subacute scans	< 0.05
Left parietal lobe	↑ ASL in those with absent BSR	< 0.05
Occipital/temporal lobes	↓ ASL in those with absent EMR	< 0.05
ASL-DWI correlation (frontal, occipital, etc.)	Positive correlation	< 0.05

ASL: Arterial spin-labeling; BSR: Absent brainstem reflexes; DWI: Diffusion-weighted imaging; EMR: Absent extensor or motor reflexes.
