GE Healthcare has launched Rediflo prefilled cartridges available with Omnipaque (iohexol) injection. The design was developed with a contrast media injector and MEDRAD Inc. The Rediflo prefilled cartridges are compatible with MEDRAD's EnVision CT and Vistron CT injection systems. 
    
A key feature of the Rediflo cartridge design is the FluiDot technology developed and patented by MEDRAD. FluiDot is an elliptical-shaped optical indicator printed on the label that denotes whether the cartridge is empty or full of contrast.  When the FluiDot is viewed through the ultra clear pharmaceutical-grade polymer cartridge filled with contrast agent, it appears perfectly round. When viewed through an empty cartridge, the FluiDot takes on an elliptical form, GE said.
