BACKGROUND AND PURPOSE: Because cerebral perfusion imaging for acute stroke is
unavailable in most hospitals, we investigated the feasibility of a method of perfusion …

BACKGROUND AND PURPOSE: PCT postprocessing commonly uses either the MS or a
variant of the DC approach for modeling of voxel-based time-attenuation curves. There is an …

By combining non-contrast-enhanced CT imaging, CT perfusion imaging, and cranial-to-
chest CT angiography (CTA), the entire cerebrovascular axis can be imaged during acute …

BACKGROUND AND PURPOSE: Numerous parameters are involved in dynamic perfusion
CT (PCT). We assessed the influence of the temporal sampling rate and the volume of …

Dynamic perfusion CT has become a widely accepted imaging modality for the diagnostic
workup of acute stroke patients. Although compared with standard spiral CT the use of …

Background Stroke management would benefit from a broadly available imaging tool that
detects perfusion deficits in patients with acute stroke. Objective To determine the role of …

PURPOSE: To assess detection of stroke and prediction of extent of infarction with
multimodal computed tomographic (CT) evaluation (unenhanced CT, perfusion CT, and CT …

The purpose of this study was to determine the prognostic accuracy of perfusion computed
tomography (CT), performed at the time of emergency room admission, in acute stroke …

A CT technique that uses equipment routinely available in most hospitals (unlike xenon-
enhanced CT) and that could provide the hemodynamic information needed for making …

Background and Purpose—In CT angiographic and perfusion imaging (CTA/CTP), rapid CT
scanning is performed during the brief steady state administration of a contrast bolus …
