Integration of Computed Tomographic Angiography Spot Sign and Noncontrast Computed Tomographic Hypodensities to Predict Hematoma Expansion.

ABSTRACT: Background and Purpose- Noncontrast computed tomographic (CT) hypodensities represent an alternative to the CT angiography spot sign (SS) to predict intracerebral hemorrhage (ICH) expansion. However, previous studies suggested that these markers predicted hematoma expansion independently from each other. We investigated whether the integration of SS and hypodensity (HD) improved the stratification of ICH expansion risk. Methods- A single-center cohort of consecutive patients with ICH was retrospectively analyzed. Patients with available CT angiography, baseline, and follow-up noncontrast CT images available were included. Trained readers reviewed all the images for SS and HD presence, and the study population was classified into 4 groups: SS and HD negative (SS-HD-), SS positive only (SS+H
