The invention provides both systems and kits for medical imaging of nerves in the head and neck of a subject.

Intra-operative head and neck nerve mapping

A method of determining the patency of a donor organ or at least one vessel to a donor organ in a donor subject includes administering a fluorescent dye to the donor subject, applying a sufficient amount of energy to the vessel such that the fluorescent dye fluoresces, obtaining a fluorescent image of the donor organ or the vessel attached to a donor organ, and observing the image to determine if a fluorescent signal is continuous through the vessel. A continuous fluorescent signal in the donor organ or vessel indicates the respective donor organ or vessel is patent.

Real time imaging during solid organ transplant

Method for assessing the patency of a patient's blood vessel, advantageously during or after treatment of that vessel by an invasive procedure, comprising administering a fluorescent dye to the patient; obtaining at least one angiographic image of the vessel portion; and evaluating the at least one angiographic image to assess the patency of the vessel portion. Other related methods are contemplated, including methods for assessing perfusion in selected body tissue, methods for evaluating the potential of vessels for use in creation of AV fistulas, methods for determining the diameter of a vessel, and methods for locating a vessel located below the surface of a tissue.

Method and apparatus for performing intra-operative angiography

The invention provides methods and systems for imaging vessels in a subject. In certain embodiments the vessels may be associated with a solid organ transplant.

The invention provides methods and systems for neurovascular imaging ().
