Indocyanine green (ICG) is a cyanine dye used in medical diagnostics. It is used for determining cardiac output, hepatic function, liver and gastric blood flow, and for ophthalmic and cerebral angiography . [ 4 ]

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.

ICGA is a safe and well-tolerated imaging study with extremely rare toxicity and allergic reactions such as nausea, vomiting, sneezing, and pruritus in 0.15% of the procedures, moderate allergic reactions such as urticaria and pyrexia in 0.2% of the patients, and severe reactions such as bronchospasm and anaphylactic reaction in 0.05% of the ...

New perfusion imaging of tissue transplants with Contrast Harmonic Ultrasound Imaging (CHI) and Magnetic Resonance Imaging (MRI) in comparison with laser-induced Indocyanine Green (ICG) fluorescence angiography.

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.

Indocyanine green (ICG) is used in innovative surgical techniques, for example to stain organs and tumor tissue, for the intraoperative imaging of flap plasty or bowel anastomosis vascularization and for the detection of sentinel lymph nodes 1, 2, 3, 4, 5, 6, 7, 8.

In vascular surgery, ICG fluorescence imaging has been studied in intraoperative assessment of graft patency, diagnostics of peripheral arterial occlusive disease and Raynaud phenomenon (RP) as well as in predicting wound healing after major amputation and to …

2023年2月16日 · In this article, we discuss the primary application of ICG fluorescence imaging in common surgical oncology, mainly focusing on sentinel lymph node biopsy (SLNB), tumor locating, imaging-guided surgical procedures, and targeted phototherapy.

Near-infrared fluorescence imaging with indocyanine green is an emerging technology gaining clinical relevance in the field of oncosurgery. In recent decades, it has also been applied in gastric cancer surgery, spreading among surgeons thanks to the diffusion of minimally invasive approaches and the related development of new optic tools.

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.
