Injection Protocol

Current protocols for pharmacologic stress MPI are complex. They require calculation of weight-adjusted dose, preparation of dose by dilution with IV fluids, syringe pump set-up, calibration, and ongoing maintenance, infusion line set-up and coordination of stress infusion with radiotracer injection.

Unlike older vasodilator pharmacological stress agents, which are administered according to a patients weight and infused over several minutes with the aid of an infusion pump, Rapiscan is administered in a single unit dose with a 10-second injection.

For Rapiscan, the overall protocol, including the administration of the radiopharmaceutical, is less than one (1) minute.
