ABSTRACT:
This invention describes how to modify a fibrin-binding protein, such as tPA, with a contrast agent, such as iodine. This substance could then be given to a patient suspected of having a blood clot by an intravenous route, and then detected by a radiographic study at a short pre-determined time later. Appropriate therapy is started immediately as determined by the radiographic study.
