Zusammenfassung
Zielsetzung: Early prediction of potential neurological recovery in patients after cardiac arrest is challenging. Recent studies suggest that the densitrometic gray-white matter ratio (GWR) determined from cranial computed tomography (CT) scans is a reliable predictor of poor outcome. We evaluated an automated, rater independent method to determine GWR in CT as an early objective imaging predictor of clinical outcome. Material und Methodik: We analyzed imaging data of 84 patients after cardiac arrest that underwent noncontrast CT within 24 hours after arrest. To determine GWR in CT we applied two methods using a…
