MRI contrast medium injection system, battery-powered
Definition
An assembly of devices designed to inject contrast media through a small catheter and into the vascular system for magnetic resonance imaging (MRI) procedures (e.g., spine, head, gastrointestinal, or vascular diagnostic procedures using MRI). It consists of battery-powered electromechanical injectors (electric motor connected to a jackscrew that moves a syringe piston) with syringes capable of delivering media with the pressure, flow range, and volume required for MRI studies, and is mobile. It may interface with the MRI system or a monitoring device to control timing of contrast injections; it is made entirely of non-ferromagnetically active materials for MRI compatiblity.
