Patent ID: 7727155

Claim:
A method of conducting a medical imaging procedure on a body or organ cavity comprising: preparing an image enhancing, viscosity-shifting composition for use in a medical imaging procedure, wherein the composition maintains an initial viscosity or consistency for a time sufficient to conduct the imaging procedure, upon or after introduction to a body or organ cavity, to remain substantially in place within the cavity, and the composition subsequently reduces in viscosity or consistency over a relatively short period of time, sufficiently so as to allow the composition to be easily expelled or removed from the cavity within about 7 to 20 minutes after the imaging procedure is completed; placing the image enhancing, viscosity-shifting composition into the body or organ cavity; conducting the imaging procedure while the composition maintains its initial viscosity; allowing the composition to then, after the procedure is completed, reduce in viscosity or consistency over the relatively short period of time; and then removing or allowing expulsion of the reduced viscosity or reduced consistency composition from the cavity after conducting the imaging procedure.
