Abstract
A process of pathology or target tissue identification comprising administering an imaging material to a pathology or target tissue bearing mammalian host and irradiating the mammalian host with electromagnetic radiation having a wavelength between about 600 and 1100 nm, and especially in the region of 700 nm and longer wavelengths, whereupon the imaging material, which has been preferentially taken up by the pathology or target tissue, emits light and permits precise identification of the location, size and/or shape of the pathology or target tissue.
