Methods We developed a graphical interface using The Visualization Toolkit, allowing for voxel selection at the confluence and bilateral internal cerebral veins on CTA along with arterial input ...

Measurement of cerebral vasoreactivity has been used to evaluate the capacity of perfusion reserve in patients with cerebral ischemia. 12345678910111213141516 Two major cerebral vasodilatory methods, ...

Advanced Neuroimaging to Guide Stroke Therapy The development and availability of CT and MRI methods has spurred efforts to use physiology to help guide the treatment of acute ischemic stroke ...

Qualitative whole-brain CT perfusion achieved 93.6% sensitivity and 92.3% specificity. CT angiography sensitivity ranged from 75.5–87.3%, while specificity held near 90% across scales.

9:43 CT perfusion for death by neurological criteria 10:43 Validation threshold 98% 11:43 Maybe adding another technique 12:43 End Transcript: Elizabeth: Is cannabis bad for your heart?

Neuroprognostication is one of the most controversial and sensitive examinations in the field of neurology.

Background: CT Perfusion (CTP) defined hemodynamic parameters used to delineate admission infarct core can be affected by truncated data acquisition, recanalization status and reactive hyperemia. We ...

Learn about vasospasm—a sudden artery narrowing that can affect the brain, heart, and extremities. Explore its causes, symptoms, and effective treatments.

Objective Blood pressure (BP) lowering may increase stroke risk in patients with symptomatic major cerebral artery disease and impaired perfusion. To investigate the relationships among BP, impaired ...

Background The purpose of this study was to evaluate the correlation between a novel angiographic score for collaterals and CT perfusion (CTP) parameters in patients undergoing endovascular treatment ...

CT-based attenuation correction is a widely used option in commercial PET/CT scanners. However, as a result of a nonsimultaneous acquisition and differences in temporal resolution between both ...
