摘要
Injection systems and related methods including an injection device, an operator interface, and modules to determine operational parameters during an MRA imaging procedure. Such parameters may be used to optimize and/or maximize signal intensity during an MRA imaging procedure. The injection system may include a target in-bloodstream contrast agent concentration determination module that determines a target in-bloodstream contrast agent concentration at least partially based on contrast agent type and MRA imager parameters. The injection system may include a contrast agent injection rate determination module that determines a contrast agent injection rate at least partially based on the target in-bloodstream contrast agent concentration, an initial contrast agent concentration, and a cardiac output rate of a patient to be imaged. The injection system may include a diluent injection rate determination module that determines a diluent injection rate at least partially based on the contrast agent injection rate.
