Contrast Media Power Injector

• For enhanceing the visibility of internal structures in X-ray-based imaging techniques such as, fluoroscopy.
• In many cases, clinicians used power injectors not only for diagnostic studies, but also for interventional procedures. 
• Fluid management injection system to inject contrast in variable mode at low flow rates and low pressures for coronary and small vessels.
• Cardiologists have commonly used power contrast media injectors to achieve opacification for these diagnostic procedures, which require high flow, high volume, fixed rate injections delivered with relatively high pressures. 
• Typical applications of this sort are: 
  • Ventriculograms
  • Aortograms 
  • Run-off studies

• Angiography uses a single-headed injectors with one syringe.
• The air embolisms are serious risks during contrast injections (inject contrast into arteries). For that reason, many cath lab injectors have air embolism detectors.
• An iodine-based contrast medium, either ionic or nonionic, is injected into the vessel. 
• For patients with negative reactions to iodine-based agents, gaseous carbon dioxide (CO2) may be used.
