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 ...
Background Predicting the final infarct after an extended time window mechanical thrombectomy (MT) is beneficial for treatment planning in acute ischemic stroke (AIS). By introducing guidance from ...
"Neither CT perfusion nor CT angiography met the prespecified threshold of greater than 98 percent for both sensitivity and specificity. Consequently, they should not be used as standalone tests ...
CT angiography visualizes blood flow within large cerebral vessels, and CT perfusion assesses tissue-level microvascular perfusion.
(D) The perfusion MRI mean transit time maps demonstrated a large perfusion abnormality in the right MCA territory, which was much larger than the diffusion abnormality (gray arrows).
“Neither CT perfusion nor CT angiography met the prespecified threshold of greater than 98 percent for both sensitivity and specificity. Consequently, they should not be used as standalone tests to ...
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 ...
The field of nuclear cardiology is witnessing growing interest in the use of cardiac PET for the evaluation of patients with coronary artery disease (CAD). The available evidence suggests that ...
