Patients excluded from this study despite DW-MRI showing the presence of HSI. Our institution's targeted temperature management protocol recommends but does not require obtaining two brain MRI scans within 6 h (first MRI) and between 72 and 96 h (second MRI) after ROSC. In this study, 4 patients showed only 1 or 2 focal HSI (orange arrow) on the ultra-early DW-MRI, and all of them did not exhibit an expanded HSI (gray arrow) area in the DW-MRI 3–4 days after ROSC. They all showed good neurological outcome, and among them, cases A, B, and D showed higher CPC scores (CPC 1) compare with case C (CPC 2). Abbreviations: CPC, cerebral performance category; DW-MRI, diffusion-weighted magnetic resonance imaging; HSI, high-signal intensity; MRI, magnetic resonance imaging; ROSC, return of spontaneous circulation
