Statistical analysis of the area under the receiver operating characteristic curve for HSI-presence in ultra-early DW-MRI. (a) Low-flow time. (b) ROSC to DW-MRI scan-interval. (c) First monitored rhythm. ROSC, return of spontaneous circulation; DW-MRI, diffusion-weighted magnetic resonance imaging; HSI, high-signal intensity; AUROC, area under the receiver operating characteristic curve.
