Diagnostic yield and spectrum of head CT findings after return of spontaneous circulation in non-traumatic in-hospital cardiac arrest: a retrospective cohort study

Head CT after IHCA was used selectively but demonstrated a high diagnostic yield. The principal contribution of this study is the characterization of current imaging practices and the clinical profile of patients who undergo CT after IHCA. Further work is needed to define which patients may benefit most from early neuroimaging and whether imaging meaningfully alters management or decision-making.
