Piston-Based Performance You Can Trust

MEDRAD® Centargo delivers the same high level and reliable performance as MEDRAD® Stellant when compared to peristaltic injectors., The piston-based design of MEDRAD® Centargo can achieve higher programmed iodine delivery rates (IDRs) and achieves the highest peak enhancement in the pulmonary artery and aorta when compared to peristaltic injectors.*

 

Maximum Achievable IDR With Medrad® Injectors

  • More consistent flow rates with piston-based MEDRAD® injectors versus tested peristaltic pumps.
  • Higher flow rates across catheter sizes.
