The number of "spot sign" on computed tomography (CT) angiography to identify patients with intracerebral hemorrhage (ICH) who are at high risk for hematoma expansion. Intracerebral hemorrhage (ICH), a CT angiography spot sign (i.e., active contrast extravasation) indicates a high risk of hematoma expansion. The computed tomogram angiography (CTA) 'spot sign' describes foci of intralesional enhancement associated with hematoma expansion in primary intracerebral hemorrhage patients.
