Indocyanine green angiography (ICGA) provides improved imaging of choroidal vasculature compared to fluorescein angiography.

2023年8月25日 · Indocyanine green angiography is an important invasive imaging modality among many diagnostic imaging modalities used in retinochoroidal diseases. It helps to study the anatomy, physiology, and pathology of choroidal and retinal circulation. It has an important role in the diagnosis of various ocular pathologies.

2024年11月19日 · When activated by a laser- or light-emitting diode, ICG fluorescence is visualized with either handheld cameras or microscopes with an integrated near-infrared imaging system. The short half-life of ICG (3–5 min) confers an excellent safety profile and allows for repeated assessments if necessary [5].

Fluorescent imaging is a relatively recent imaging method and thus still developing in many ways. This is especially true for indocyanine green (ICG) imaging in its new clinical applications recently proposed in various branches of surgical medicine, although it has been used in some clinical applications routinely already for almost sixty years.

2023年4月28日 · 吲哚菁绿（ICG）可被波长750～810 nm的近红外光激发，发射波长840 nm左右的荧光，其组织穿透深度为5～10 mm。 ICG荧光成像技术自2008年被首次报道用于肝脏外科以来，在肝脏肿瘤染色、解剖性肝切除术、肝内外胆道显影、肝脏移植等方面展现出重要的临床价值及广阔的应用前景[1-2]。 近年来，随着新型荧光成像系统尤其是荧光腹腔镜的快速发展，ICG荧光成像技术在国内外广泛应用。

To tackle the concern, this paper puts forward a deep learning method named Denoising Diffusion Probabilistic Model Self-supervised Knowledge Distillation Net (DDPM-SKDNet) for the ICG images classification task, by incorporating a contrastive learning based approach as the network architecture and using DDPM as the image generator in the ...

2022年9月1日 · Indocyanine green (ICG) is a visible fluorescent tricarbocyanine dye with near infra-red (NIR) or laser systems, which was approved by the Food and Drug Administration in 1956. 2.

Indocyanine Green Chorioangiography (ICG) is a procedure which images a layer of the posterior part of the eye. This layer, the choroid, is deeper than the retina and normally obscured by pigmentation. The choroid contains a unique network of blood vessels.

2024年7月20日 · 吲哚菁绿（Indocyanine Green，简称ICG）是一种在生物医学成像领域具有重要应用的荧光染料。 由于其特定的光学性质，尤其是在近红外区域的吸收和发射特性，ICG在生物成像中显示出独特优势。

2025年2月13日 · Angiographic images from a patient with multiple evanescent white dot syndrome (MEWDS) using fluorescein (A) and indocyanine green (B) contrast agents. Note the different response of the lesions to the 2 agents. The spots that appear bright on the FA image appear dark on the ICG image.
