OCTA in Mild Cognitive Impairment and Alzheimer's Disease

This study aims to develop and evaluate biomarkers using non-invasive optical coherence tomography angiography (OCTA) to assess the structure and function of the retinal microvasculature i...

Optical Coherence Tomography Angiography Examinations in Chronic Retinal Artery Occlusion

Purpose of the study is to examine the retinal blood flow in chronic cases of retinal artery occlusion with non-invasive, non-contact optical coherence tomography angiography.

The Relationship Between Macular OCTA and GCIPL and Their Combinational Index Using AI

Macular GCIPLT and vessel density will be measured with Spectralis optical coherence tomography and Topcon swept-source OCT respectively. Linear, quadratic and exponential regression model...

Multimodal Imaging of Retinal Vessels

Retinal blood flow measurement is of scientific and clinical value. For this purpose retinal vessel morphology (such as diameter, vessel wall thickness, etc) determination is crucial. Diff...

Optical coherence tomography angiography: Value for glaucoma diagnostics.

Optical coherence tomography angiography (OCTA) is a novel noninvasive method which enables a quantitative evaluation of retinal and optic nerve head (ONH) perfusion. In this article, we discuss the...

SWEPT-SOURCE OPTICAL COHERENCE TOMOGRAPHY AND OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY FINDINGS IN WAARDENBURG SYNDROME.

Waardenburg syndrome (WS) is a rare condition characterized by six main features. It has been previously observed that WS is also associated with hypopigmentation of the choroid through multimodal ima...

Quantitative Comparison of Retinal Vascular Features in Optical Coherence Tomography Angiography Images From Three Different Devices.

To compare optical coherence tomography angiography (OCTA) images from three different devices.

Cataract significantly influences quantitative measurements on swept-source optical coherence tomography angiography imaging.

To analyze retinal blood flow before and after cataract surgery using swept-source optical coherence tomography angiography (SS-OCTA).

OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IMAGING OF A CONGENITAL SIMPLE HAMARTOMA OF THE RETINAL PIGMENT EPITHELIUM.

To report the case of a small pigmented tumor in the macular region investigated using optical coherence tomography angiography (OCT-A) in the context of a multimodal approach.

Medical and Biotech [MESH] Definitions

An imaging method using LASERS that is used for mapping subsurface structure. When a reflective site in the sample is at the same optical path length (coherence) as the reference mirror, the detector observes interference fringes.

The use of light interaction (scattering, absorption, and fluorescence) with biological tissue to obtain morphologically based information. It includes measuring inherent tissue optical properties such as scattering, absorption, and autofluorescence; or optical properties of exogenous targeted fluorescent molecular probes such as those used in optical MOLECULAR IMAGING, or nontargeted optical CONTRAST AGENTS.

A radionuclide imaging agent used primarily in scintigraphy or tomography of the heart to evaluate the extent of the necrotic myocardial process. It has also been used in noninvasive tests for the distribution of organ involvement in different types of amyloidosis and for the evaluation of muscle necrosis in the extremities.

Descriptive anatomy based on three-dimensional imaging (IMAGING, THREE-DIMENSIONAL) of the body, organs, and structures using a series of computer multiplane sections, displayed by transverse, coronal, and sagittal analyses. It is essential to accurate interpretation by the radiologist of such techniques as ultrasonic diagnosis, MAGNETIC RESONANCE IMAGING, and computed tomography (TOMOGRAPHY, X-RAY COMPUTED). (From Lane & Sharfaei, Modern Sectional Anatomy, 1992, Preface)

Non-invasive method of vascular imaging and determination of internal anatomy without injection of contrast media or radiation exposure. The technique is used especially in CEREBRAL ANGIOGRAPHY as well as for studies of other vascular structures.
