Identifying Parathyroid Glands: Challenges & Innovations

[Dr. Michael Singer] What happens with fluorescence imaging is you inject say an agent like indocyanine green that flows to the tissue. Then in fluorescence imaging, what happens is you have say a camera. The camera is stimulating that agent at a certain wavelength of light, and that then gives off a different wavelength of light, which can be say picked up by a camera. Again, some of your listeners are probably familiar with this, ICG is pretty commonly used now in surgical fields, whether in plastic surgery, colorectal surgery, any of your listeners who do say free flaps will probably be familiar with this. That's used for looking at vascularity of tissue, okay?
