indocyaningröda
Indocyaningröda, more commonly known as indocyanine green (ICG), is a water-soluble cyanine dye used in medical imaging. It absorbs near-infrared light and emits fluorescence, enabling visualization of vascular structures and tissues beneath the surface. When injected intravenously, ICG binds to plasma proteins, remaining largely within the bloodstream and emitting light detectable by specialized imaging systems.
Pharmacology and properties: ICG has a peak absorption around 800 nm and emits fluorescence near 830 nm,
Clinical uses: ICG is employed in ophthalmology for retinal and choroidal angiography, in hepatobiliary function testing
Safety and limitations: ICG is generally well tolerated, but rare adverse reactions including hypersensitivity and anaphylactoid
Regulatory status: ICG is approved for diagnostic imaging in many countries and is used under medical supervision.
