Abstract
The present invention relates to the use of particulate materials as contrast agents in in vivo light imaging.
Claims34
A method of generating an image of the human or non-human animal body by light imaging, characterised in that a physiologically tolerable particulate contrast agent is administered to said body and an image of at least part of said body is generated.
A method as claimed in any one of the previous claims wherein said image is of vasculature in said body.
A method as claimed in any one of the previous claims wherein said image is of a phagocytic organ in said body.
Use of a physiologically tolerable particulate material for the manufacture of a particulate contrast agent containing contrast medium for use in in vivo diagnostic light imaging.
A dignostic imaging composition comprising a physiologically tolerable particulate agent comprising solid particles coated with a photolabel having a molar absorptivity of at least 105 cm−1 M−1 and an absorption maximum in the range 300 to 1300 nm.
