What is vivo fluorescence imaging?
What is vivo fluorescence imaging?
In vivo fluorescence imaging uses a sensitive camera to detect fluorescence emission from fluorophores in whole-body living small animals. Further emerging developments are aiming to achieve high-resolution, multimodality and lifetime-based in vivo fluorescence imaging.
Is imaging in vivo?
In vivo imaging is the non-invasive visualization of living organisms for research or diagnostic purposes. In molecular imaging cellular function or molecular processes are visualized, normally using biomarkers.
What is in vivo fluorescence?
In vivo fluorescence microscopy is an imaging technique that uses fluorescence to image cells within live organisms. This type of microscopy provides highly accurate results and allows for the observation of the development of certain processes.
How does in vivo imaging work?
In vivo imaging is the non-invasive visualization of living organisms for research and/or diagnostic purposes. This method can be divided in two key areas: anatomical/morphological imaging and molecular imaging. In molecular imaging cellular function or molecular processes are visualized using biomarkers.

What does IVIS stand for?
IVIS
| Acronym | Definition |
|---|---|
| IVIS | in Vehicle Information System |
| IVIS | In Vivo Imaging System (veterinary imaging technology) |
| IVIS | Interactive Video Information System |
| IVIS | Intervehicular Information System |
How does IVIS Spectrum work?
IVIS acquires a photographic image of the animal under white light and a quantitative bioluminescent or fluorescent signal, which is overlaid on the image. The image display is adjusted to provide optimal contrast and resolution in the image without affecting quantitation.
How does BLI imaging work?
Bioluminescence imaging (BLI) is a technology that uses light emitted by enzyme-catalyzed reactions to report activity at the molecular level. Bioluminescent reporters require a small chemical substrate for non-invasive imaging in cell biology and small animal studies.
What is the difference between in vitro and in vivo?
In vivo refers to when research or work is done with or within an entire, living organism. In vitro is used to describe work that’s performed outside of a living organism. This can include studying cells in culture or methods of testing the antibiotic sensitivity of bacteria.
Where is luciferin found?
Luciferases comprise a group of enzymes that emit light in the presence of oxygen and a substrate (luciferin). Such a luciferin–luciferase system is found in nature, for example, in bacteria (Vibrio harveyi), dinoflagellates (Gonycaulax), and the firefly (Photinus pyralis).
What does IVIS mean?
What is bioluminescence tomography?
Bioluminescence imaging (BLI) is a technology developed over the past decade that allows for the noninvasive study of ongoing biological processes. Recently, bioluminescence tomography (BLT) has become possible and several systems have become commercially available.
What are some examples of in vivo near-infrared fluorescence imaging?
Recent examples of in vivo near-infrared fluorescence imaging of animals and humans are presented, including imaging of normal and diseased vasculature, tissue perfusion, protease activity, hydroxyapatite and cancer. This review focuses on recently published examples of in vivo near-infrared (NIR) fluorescence imaging.
How do tissue absorption and scatter affect NIR fluorescence imaging?
A detailed analysis of how tissue absorption and scatter affect the selection of excitation and emission wavelengths for reflectance in vivo NIR fluorescence imaging has recently been published [3 ••]. Because there is little NIR fluorescence contrast generated by most tissues, most in vivo studies administer exogenous contrast agents.
How does NIR light reduce autofluorescence?
Use of a NIR filter set essentially eliminates autofluorescence. Hence, high tissue autofluorescence precludes the use of visible light for most in vivo imaging applications, and NIR light solves this problem by reducing fluorescence background. Figure 1. Wavelength-dependent autofluorescence of vital organs and bodily fluids.
Why are exogenous contrast agents used in in vivo studies?
Because there is little NIR fluorescence contrast generated by most tissues, most in vivo studies administer exogenous contrast agents. Until recently, exogenous contrast was limited to organic fluorophores, the most common of which are polymethines.
