Neither computed tomography (CT) perfusion nor CT angiography meet the prespecified validation threshold as an ancillary test for death by neurologic criteria (DNC) in critically ill patients.

Hypoxia occurs in various pathophysiological conditions. Especially, brain can be seriously affected by the oxygen deficiency. However, challenges exist in optically monitoring cerebral hemodynamics ...

Brain Aneurysm Diagnosis A brain aneurysm is often discovered after it has ruptured or by chance during diagnostic exam, such as computed tomography (CT scan), magnetic resonance imaging (MRI), or ...

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

Cerebral blood flow (CBF) alterations are important in pathogenesis of neonatal ischemic/hemorrhagic brain damage. In clinical practice, estimation of neonatal CBF is mostly based on Doppler ...

Objectives The purpose of this pilot study was to obtain baseline quantitative pupillometry (QP) measurements before and after catheter-directed cerebral angiography (DCA) to explore the hypothesis ...

Swelling in the brain (hydrocephalus) is one of the possible problems. It's caused by the buildup of CSF and blood between the brain and skull. This can increase the pressure on the brain. A ...

Background The transradial approach for endovascular angiography and interventional procedures is superior to the traditional transfemoral approach in several metrics, including lower access-site ...

Investigations Neurological examination, brain MRI scan, lumbar puncture, four-vessel cerebral angiogram and spinal angiogram. Diagnosis Superficial siderosis; a complete review of the current ...

A cerebral angiogram showed no evidence of aneurysm or vascular malformation. She had no coagulopathy. One month later she again presented with headache. CT showed progression of her hemorrhage.

Background and Purpose We tested the hypothesis that cerebral hypoxia-ischemia selectively stimulates interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) gene expression in brain regions ...
