Abstract
A syringe for use with an injector includes a body comprising a distal discharge end, a plunger movably disposed within the body, and an agitation element disposed within the body between the plunger and the distal discharge end. The agitation element is acted on by a magnetic field to agitate the contents of the syringe. The magnetic field is generated by a source operably associated with the syringe or the injector. Preferably, the syringe contains an ultrasound contrast agent that is agitated by the agitation element. An injector system and a method for agitating the contents of a syringe are also provided.
