BACKGROUND AND PURPOSE: Various CTP parameters have been used to identify
ischemic penumbra. The purpose of this study was to determine the optimal CTP parameter …

Computed tomography (CT) plays a pivotal role in the diagnosis of acute stroke and in
treatment decision making. CT perfusion imaging performed with intravenous iodinated …

Background and Purpose—This study aims to determine whether perfusion computed
tomographic (PCT) thresholds for delineating the ischemic core and penumbra are time …

BACKGROUND AND PURPOSE: Although CT perfusion is a promising tool to support
treatment decisions for patients with acute ischemic stroke, it still lacks a standardized …

The aim was to evaluate a novel method of threshold-free prediction of brain infarct from
computed tomography perfusion (CTP) imaging in comparison to conventional ischemic …

Background and Purpose—Magnetic resonance imaging (MRI)-based perfusion measures
using dynamic susceptibility contrast are extremely useful for identification of ischemic …

Background and Purpose—Different definitions have been proposed to define the ischemic
penumbra from perfusion-CT (PCT) data, based on parameters and thresholds tested only in …

CT perfusion (CTP) is part of the initial evaluation of stroke patients, allowing differentiation
between infarcted tissue and the ischaemic penumbra and helping in the selection of …

Background Computed tomography perfusion (CTP) mapping in research centers correlates
well with diffusion-weighted imaging (DWI) lesions and may accurately differentiate the …

Background and Purpose—We investigated whether computed tomography (CT) perfusion–
derived cerebral blood flow (CBF) and cerebral blood volume (CBV) could be used to …
