A method is provided for localizing an internal bleeding site whereby a protein or other factor involved in the clotting process is complexed to an imaging agent and injected into a patient believed to be at risk of internal bleeding. A clot in the patient will naturally accumulate a certain concentration of the injected complex, and within a short period of time the concentration becomes sufficient to be detected by an imaging apparatus. The imaging contrast agent may, for example, be an MRI contrast agent, a CT contrast agent, a PET agent, or a fluorescent substance.
