Advanced CT Imaging in the Evaluation of Hemorrhagic Stroke

Multidetector computed tomographic (CT) angiography is rapidly becoming a pivotal examination in the initial evaluation of patients with hemorrhagic stroke. This article provides an update of the literature on this dynamic topic, focusing on (1) the utility of CT angiography in the identification of hemorrhagic stroke patients who harbor an underlying vascular etiology and the role of the secondary intracerebral hemorrhage score, as well as (2) the clinical value of the CT angiography spot sign and spot sign score in patients with primary intracerebral hemorrhage.
