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.

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 ...

Aqueous angiography imaging offer surgeons an in vivo evaluations that can aid in the workup for minimally-invasive glaucoma surgeries.

A substudy reports that optical coherence tomography resulted in less vessel failure after percutaneous coronary angioplasty ...

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 ...

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.

Existing two-dimensional cell cultures and stem cell-derived organoids have shown significant limitations in reproducing the complex architecture and function of the brain. To overcome these ...

Background and Purpose—Limited data exist to recommend specific cerebral perfusion pressure (CPP) targets in patients with intracerebral hemorrhage. We sought to determine the feasibility of brain ...

Abstract: This paper describes a multistage perceptual quality assessment (MPQA) model for compressed images. The motivation for the development of a perceptual quality assessment is to measure ...
