Fig. 1 — Correlations between Bayesian parameters, diffusion lesion volume and the angiographic collateral grading (0–1 vs 2 vs 3–4) in the whole cohort. VolATD6 and VolDWI have the highest correlation with the angiographic collateral grading. More extensive collaterals significantly correlate with smaller baseline volume of tissue with severely increased ATD and smaller baseline DWI lesion volume (Spearman’s rank correlation)
