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

Acute stroke is a major cause of mortality and the leading cause of adult disability in the
United States. 1. In adults, 87% of acute stroke is caused by compromised blood flow with …

Materials and Methods Four circular phantoms of different diameter (10–40 cm) with an
iodine insert at the center were scanned at a fixed radiation dose with different single-(80 …

Background and purpose To evaluate whether brain CT perfusion (CTP) aids in the
detection of intracranial vessel occlusion on CT angiography (CTA) in acute ischemic stroke …

Objectives In acute stroke patients with large vessel occlusion, collateral blood flow affects
tissue fate and patient outcome. The visibility of collaterals on computed tomography …

Background and Purpose—The length of large vessel occlusion is considered a major factor
for therapy in patients with ischemic stroke. We used 4D-CT angiography evaluation of …

Objectives To compare collateral status on single-phase CT angiography (sCTA) and
multiphase CT angiography (mCTA) and their ability to predict a target mismatch on CT …

BACKGROUND AND PURPOSE: In patients with acute stroke, the location and extent of
intravascular thrombi correlate with clinical and imaging outcomes and have been used to …

Background and Purpose—Patient selection is crucial in the endovascular treatment of
acute ischemic stroke patients. Baseline computed tomographic (CT) images, evaluated with …

OBJECT This prospective study investigated the role of whole-brain CT perfusion (CTP)
studies in the identification of patients at risk for delayed ischemic neurological deficits …
