The present invention describes a method of concurrent imaging in a mammal
comprising: a) administering to said mammal a vitronectin receptor
targeted imaging agent and a perfusion imaging agent; and b) concurrently
detecting the vitronectin target imaging agent bound at the vitronectin
receptor and the perfusion imaging agent; and c) forming an image from
the detection of said vitronectin receptor targeted imaging agent and
said perfusion imaging agent.
