Purpose To perform a large-scale systematic comparison of the accuracy of all commonly
used perfusion computed tomography (CT) data postprocessing methods in the definition of …

Stroke is a leading cause of death and disability worldwide. Imaging plays a critical role in
evaluating patients suspected of acute stroke and transient ischemic attack, especially …

The imaging management of acute ischemic stroke remains challenging both diagnostically
and therapeutically. Intravenous tissue plasminogen activator (tPA)(to be used within 4.5 …

Rapid advance in medical technology has resulted in the availability of numerous tests and
treatment strategies in the management of acute stroke. The increasingly evidence-based …

Background The aim of this study was to investigate the feasibility of ischemic stroke
detection from computed tomography angiography source images (CTA-SI) using three …

There is no consensus on how the reliability and predictive ability of noncontrast computed
tomography (NCCT) and computed tomography angiography source image (CTASI) change …

Background and Purpose—Alberta Stroke Programme Early CT Score (ASPECTS) is widely
used for assessment of early ischemic changes in acute stroke. We hypothesized that CT …

Purpose To test whether the relationship between acute ischemic infarct size on concurrent
computed tomographic (CT) angiography source images and diffusion-weighted (DW) …

Background and Purpose—Futile recanalization after acute ischemic stroke occurs in almost
half of the patients despite optimal angiographic results. Multimodal neuroimaging may help …

The accurate identification of irreversible infarction and salvageable tissue is important in
planning the treatments for acute ischemic stroke (AIS) patients. Computed tomographic …
