Real‐World Performance of CSF Kappa Free Light Chains in the 2024 McDonald Criteria

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Kappa free light chains (KFLCs) in the cerebrospinal fluid (CSF) have a similar performance to CSF‐restricted oligoclonal bands (OCB) for multiple sclerosis (MS) diagnosis. To help with implementation, we set out to resolve several remaining uncertainties: (1) performance in a real‐world cohort and the 2024 McDonald criteria; (2 ...

High-speed optical coherence manipulation based on lithium niobate films modulator

PhotoniX
Research on the optical coherence manipulation has made significant progress, but the modulation rate of conventional tailoring technology is too low, which has become a key factor hindering its transition from laboratory to practical application.

Investigation of Light Parameters on Image Quality and Optical Coherence Tomography

International Journal of Optics, 2021
In this work, image quality and optical coherence tomography were studied. The results of the study show that there is a very significant difference between ultrasound and optical coherence tomography to produce an image with a different wave.

Absence of Long-Range Coherence in the Parametric Emission from Photonic Wires

, 2006
We analytically investigate the spatial coherence properties of the signal emission from one-dimensional optical parametric oscillators. Because of the reduced dimensionality, quantum fluctuations are able to destroy the long-range phase coherence even ...

Coherence and Efficiency in Nonlinear Optical Processes [PDF]

, 1972
A remarkable difference between linear and nonlinear processes lies in the fact that the efficiency of the latter depends on the coherence properties of the electromagnetic field (pump) from which the process is ...

Optical coherence tomography

Journal of Biomedical Optics, 1996
This paper gives an introduction to optical coherence tomography (OCT), explains its basic principles, and discusses the information content of OCT images. Various interferometric techniques used in OCT are reviewed and a short survey of results obtained so far in different fields of application and possible future developments are presented.

Optical coherence angiography

Medicine, 2016
Retinal vascular diseases are one of the most common causes of blindness in the developed world. Optical Coherence Tomography Angiography (OCT-A) is a new noninvasive method that uses several algorithms to detect blood movement. This enables the creation of high-resolution vascular images with contrast depicting motionless tissue.This review presents ...
