Imaging plays a central role for intravenous and intra-arterial arterial ischemic stroke
treatment patient selection. Computed tomography (CT)/CT angiography or magnetic …

Recent positive trials have thrust acute cerebral perfusion imaging into the routine
evaluation of acute ischemic stroke. Updated guidelines state that in patients with anterior …

Background In most countries, alteplase given within 4· 5 h of onset is the only approved
medical treatment for acute ischaemic stroke. The newer thrombolytic drug tenecteplase has …

Cerebral small vessel disease (SVD) gives rise to one in five strokes worldwide and
constitutes a major source of cognitive decline in the elderly. SVD is known to occur in …

Purpose To validate the use of perfusion computed tomography (CT) with whole-brain
coverage to measure the ischemic penumbra and core and to compare its performance to …

Tools for medical image analysis have been developed to reduce the time needed to detect
abnormalities and to provide more accurate results. Particularly, tools based on artificial …

Figure 1. Matched and Mismatched perfusion computed tomography (PCT) imaging in a
patient with middle cerebral artery (MCA) occlusions. Noncontrast head CT (NCCT) and …

Purpose To design a digital phantom data set for computed tomography (CT) perfusion and
perfusion-weighted imaging on the basis of the widely accepted tracer kinetic theory in …

Objective Many patients with stroke cannot receive intravenous thrombolysis because the
time of symptom onset is unknown. We tested whether computed tomography (CT)‐based …

Whole brain computed tomography perfusion (CTP) has the potential to select eligible
patients for reperfusion therapy. We aimed to find the optimal thresholds on baseline CTP for …
