Optical coherence tomography angiography with adaptive multi-time interval 自适应多时间间隔的光学相干断层扫描血管造影术 鉴知技术 光学相干层析成像(Optical Coherence Tomography,OCT)是一种无损、无标记、高分辨和非侵入式的光学成像方法。OCT因其微米级高分辨率、高穿透深度和超快成像速度等特点,在诸多生物成像技术...
optical coherence tomography angiographyOptical coherence tomography angiography (OCTA) is a sophisticated ophthalmic imaging technique, enables us to obtain images of blood vessels and blood flow at different levels of the retina and choroid without the use of contrast. Therefore, its potential ...
Optical coherence tomography (OCT) is a non-invasive, non-contact imaging modality which provides high resolution, cross-sectional images of the retina and is ubiquitous in ophthalmology practice to diagnose and monitor retinal disorders1. OCT angiography (OCTA) uses moving red blood cells in the r...
Optical coherence tomography angiography (OCTA) is a new, non-invasive imaging system that generates volumetric data of retinal and choroidal layers. It has the ability to show both structural and blood flow information. Split-spectrum amplitude-decorrelation angiography (SSADA) algorithm (a vital com...
Optical coherence tomography angiography is a novel imaging technique that allows dyeless in vivo visualization of the retinal and choroidal vasculature. The purpose of this study was to describe optical coherence tomography (OCT) angiography findings in patients with retinal arterial macroaneurysms (RAMs...
目的:使用光学相干断层扫描血管造影术(Optical Coherence Tomography Angiography, OCTA)对白内障术后黄斑囊样水肿患者的黄斑区视网膜厚度及血流情况进行研究.材料:本研究为前瞻性研究,收集2017年4月到2018年2月期间就诊于青岛大学附属医院眼科的白内障术后黄斑囊样水肿患者20例20只眼,正常白内障术后患者20例20只眼,利用...
Optical coherence tomography angiography (OCTA) has demonstrated good utility in qualitative analysis of retinal and choroidal vasculature and therefore may be relevant in the diagnostic and treatment efforts surrounding nonarteritic anterior ischemic optic neuropathy (NAION).Retrospective, cross-sectional stud...
Optical coherence tomography angiography in cognitively impaired patients: Vascular and neurodegenerative perspectives: Biomarkers (non‐neuroimaging) / Novel biomarkersVascular and neuronal changes in the retina may reflect cerebral small vessel disease (CSVD) and neurodegeneration in the brain. We aimed to...
Recently, applications of optical coherence tomography angiography (OCTA) have been limited to the retina and posterior segment. Although early studies have described its use for other clinical applications, its role in anterior segment vasculature and optic disc imaging has been limited thus far. We...
To analyze foveal avascular zone (FAZ) dimensions and symmetry in patients with diabetic retinopathy (DR) compared to healthy controls using optical coherence tomography angiography (OCT angiography). OCT angiography was performed via an Avanti RTVue 100 XR OCT system (Optovue, Inc., Fremont, CA, ...
