A device for gathering image information about a region of tissue that has been exposed to a contrast agent and methods of use thereof. The device preferably includes night vision goggles, and an excitation source that generates light of a wavelength to activate the contrast agent. The excitation source preferably is attached to the night vision goggles and is capable of directing light to a target. A filter preferably is attached to the night vision goggles, wherein the filter passes light sufficient to form an image of the region of tissue, and wherein the image may be assessed to determine the viability of the region of tissue. |
