Role of Spot Sign on CT Angiography to Predict Hematoma Expansion in Spontaneous Intracerebral Hemorrhage

摘要

ObjectivePatients with spontaneous intracerebral hemorrhage (ICH) presenting within 24 hours of symptom onset are known to be increased risk of hematoma expansion which is closely correlated with morbidity and mortality. We investigated whether tiny enhancing foci ('Spot sign') on axial view of 3-dimensional computed tomography angiography (3D-CTA) source images can predict subsequent hematoma expansion in spontaneous ICH.
