Optimize Contrast with the Imaging Bulk Package Transfer Set
Streamline preparation and optimize in-suite operations with MEDRAD Stellant FLEX and the Imaging Bulk Package
Transfer Set.
Choose Your Contrast
The transfer set is FDA-cleared for use with three iodinated contrast agents in approved imaging bulk packages (IBP).
Improve Workflow Efficiency
Reduces preparation steps for patient injection and may reduce contrast waste vs. single-dose vials.2
Consider Joint Commission Standards
Bayer specialists understand Joint Commission expectations and industry best practices, and will support you through seamless implementation and everyday use of our products.
Contrast-Enhanced Mammography (CEM)
The first and only CT injection system currently 510(k) cleared for use with CEM.
- Accurate contrast dose administration for better visualization of abnormalities in the breast tissue that may not be visible with conventional mammography3
- Consistent contrast delivery for enhanced visualization of breast lesions3
- Small footprint and flexible movement allow for various room configurations*
*Maintain a 4.9ft (1.5m) safe distance between the patient and non-patient devices. Install the workstation (non-patient device) a minimum of 4.9ft (1.5m) from the injector head.
