Diagnostic utility of CT Hounsfield unit for accurate classification of ischemic and haemorrhagic stroke

Year: 2025

Type: article

Abstract: This study examines the diagnostic value of Hounsfield Unit (HU) measurements on computed tomography (CT) in differentiating ischemic from haemorrhagic stroke, a distinction critical for timely and appropriate clinical intervention. The study aims to quantify HU values for both stroke types and assess their correlation with stroke lesion size and volume. Non-contrast enhanced CT brain images were retrospectively reviewed from the PACS. HU values, demographic characteristics, clinical risk factors, and stroke classifications were analysed quantitatively. The results demonstrated a lower mean HU value in ischemic strokes (24.37 ± 5.85) compared with haemorrhagic strokes (57.17 ± 20.10). Lesion volume was significantly correlated with haemorrhagic stroke (r = 0.829, p = 0.041). These findings highlight the utility of HU values as a potential imaging marker for distinguishing ischemic from haemorrhagic stroke. This may improve diagnostic accuracy and support more informed clinical decision-making, hence contributing to better stroke assessment and management.
