OBJECT Near-infrared spectroscopy (NIRS) offers noninvasive bedside measurement of direct regional cerebral arteriovenous (mixed) brain oxygenation. To validate the accuracy of this monitoring technique, the authors analyzed the statistical correlation of NIRS and CT perfusion with respect to regional cerebral blood flow (CBF) measurements. METHODS The authors retrospectively reviewed all cases in which NIRS measurements were obtained at a single, academic neurointensive care unit from… Expand
Can Cerebral Near-infrared Spectroscopy Predict Cerebral Ischemic Events in Neurosurgical Patients? A Narrative Review of the Literature.
TLDR
The evidence on the selected studies is not strong enough, at the moment, to recommend cerebral NIRS as a mandatory monitor to detect cerebral deoxygenation able to predict the future neurological outcome in neurosurgical patients. Expand
Comparison of Cerebral Oxygen Saturation and Cerebral Perfusion Computed Tomography in Cerebral Blood Flow in Patients with Brain Injury.
TLDR
A statistically significant correlation was found between SctO2 level and cerebral blood volume (CBV) level (R=0.9; p<0.000001). Expand
Application of Near-Infrared Spectroscopy for the Detection of Delayed Cerebral Ischemia in Poor-Grade Subarachnoid Hemorrhage
TLDR
Cerebral regional oxygen saturation (rSO2) was continuously monitored via two-channel NIRS for 14 days following SAH and near-infrared spectroscopy shows some promising results for the detection of DCI in patients with poor-grade SAH. Expand
Continuous-wave near-infrared spectroscopy is not related to brain tissue oxygen tension
TLDR
Near-infrared spectroscopy has gained acceptance for cerebral monitoring, especially during cardiac surgery, though there are few data showing its validity, and CW-NIRS should not be used for the detection of cerebral ischemia. Expand
Cerebral Near-Infrared Spectroscopy: A Potential Approach for Thrombectomy Monitoring
TLDR
RSO2 was merely correlated with baseline Tmax and mean transit time magnetic resonance imaging perfusion parameters and the relationship between rSO2 changes, recanalization, and clinical outcome was not correlated with clinical outcome. Expand
Improving the quantitative accuracy of cerebral oxygen saturation in monitoring the injured brain using atlas based Near Infrared Spectroscopy models.
TLDR
Using registered Atlas models in simulation, a novel method is outlined by which the quantitative accuracy and practicality of NIRS for specific use in monitoring the injured brain, can be improved, with cerebral saturation being recovered to within 10.1 ± 1.8% of the expected values. Expand
Noninvasive Cerebral Oximetry during Endovascular Therapy for Acute Ischemic Stroke: An Observational Study
TLDR
The findings suggest that bi-channel rSO2-NIRS has potential for guiding neuroanesthesia and predicting outcome and to better monitor local revascularization, an improved stroke-specific set-up in future studies is necessary. Expand
The physiological determinants of near-infrared spectroscopy-derived regional cerebral oxygenation in critically ill adults
TLDR
Known and established physiological determinants of oxygen delivery accounted for a significant proportion of the rSO2 signal, which provides evidence that NIRS is a viable modality to assess cerebral oxygenation in critically ill adults. Expand
The future of non-invasive cerebral oximetry in neurosurgical procedures: A systematic review
TLDR
A systematic review synthesizes the most current evidence of non-invasive, inexpensive, and continuous measurement of cerebral oxygenation by NIRS and shed light on how this neuromonitoring technique is beneficial in preventing perioperative neurological complications. Expand
Assessment of the Brain's Macro- and Micro-Circulatory Blood Flow Responses to CO2 via Transfer Function Analysis
TLDR
The transfer function characterizes the blood flow transition from macro- to micro-circulation by time delay only and offers the prospect of a more detailed grading of CA responses. Expand

Bedside assessment of cerebral perfusion reductions in patients with acute ischaemic stroke by near-infrared spectroscopy and indocyanine green.
TLDR
Measurement of interhemispheric differences in ICG kinetics by NIRS detects perfusion reductions in patients with acute middle cerebral artery infarction, and is rapid, repeatable, without major side effects, and avoids transportation of critically ill patients. Expand

A near infrared spectroscopy (NIRS) system that allows for quantitative, bedside measurement of cerebral blood flow (CBF), cerebral blood volume (CBV), and mean transit time (MTT) is developed. Expand
Cerebral Hemoglobin and Optical Pathlength Influence Near-Infrared Spectroscopy Measurement of Cerebral Oxygen Saturation
TLDR
Data indicate that intersubject variability in NIRS originates, in part, from biologic variations in transcranial optical pathlength and cerebral hemoglobin concentration, and Instruments to account for these factors may improve N IRS cerebral oxygen saturation measurements. Expand
Cerebral perfusion CT: technique and clinical applications.
TLDR
The technique has been found to be useful for noninvasive diagnosis of cerebral ischemia and infarction and for evaluation of vasospasm after subarachnoid hemorrhage and for assessment of microvascular permeability in patients with intracranial neoplasms. Expand

TLDR
Preserved cerebral and cerebellar perfusion in the chronic population may in part be due to the effects of antipsychotic treatment which may have normalized blood volume and flow, and Hypoperfusion in relation to chronicity, particularly in the frontal lobe. Expand

Several clinical conditions routinely encountered in daily practice have the potential to disrupt the balance between the brain oxygen supply and demand, exposing to the risk of intraoperative cerebral ischemia. Expand

Real-time analysis of cerebral physiologic, metabolic, and cardiovascular parameters simultaneously has broadened knowledge about complex brain pathophysiology and cerebral hemodynamics and allows for more precise diagnosis and optimization of management of patients with brain injury. Expand

While PWI currently is not able to replace XeCT in the direct quantification of CVRC, it may serve as a readily available follow-up tool and an approximative equation to calculate the probability of pathological findings could be derived from the data. Expand
