Background: Cerebral computed tomography (CT) and various severity
scoring systems have been developed for the early prediction of the neurological
outcomes of cardiac arrest survivors. However, few studies have combined these
approaches. Therefore, we evaluated the value of the combination of cerebral CT
and severity score for neuroprognostication. Methods: This
single-center, retrospective observational study included consecutive patients
surviving nontraumatic cardiac arrest (January 2016 and December 2020).
Gray-to-white ratio (GWR), third and fourth ventricle characteristics, and medial
temporal lobe atrophy scores were evaluated on noncontrast cerebral CT.
Simplified cardiac arrest hospital prognosis (sCAHP) score was calculated for
severity assessment. The associations between the CT characteristics, sCAHP score
and neurological outcomes were analyzed. Results: This study enrolled
559 patients. Of them, 194 (34.7%) were discharged with favorable neurological
outcomes. Patients with favorable neurological outcome had a higher GWR (1.37 vs
