MEDRAD® Stellant
Intelligent and intuitive – MEDRAD® Stellant is the injector of choice for advanced CT applications providing accurate personalized delivery of contrast.*
Clear Direction. Boost Your Image.
MEDRAD® Stellant enables the flexibility of injecting contrast and saline – offering many clinical and workflow advantages, such as: using saline to perform a patency check, reducing image artifacts and providing brighter arterial imaging in CT.1,2
What is MEDRAD® Stellant?
MEDRAD® Stellant is a contrast media injection system designed for use during CT examinations, known for its innovative clinical offerings and feature set. It is the injector of choice for advanced CT applications such as cardiac and perfusion imaging.
How does MEDRAD® Stellant work?
The intuitive touch screen interface allows the user to set the injection protocol needed for the CT examination. MEDRAD® Stellant gives the user the option to store and recall up to 250 CT injection protocols for fast access. Injection protocols are easily adjusted to suit the individual patient by simply selecting the parameter to be changed and entering in the new value. Up to 6 injection phases can be programmed depending upon the area to be imaged.
Contrast Delivery
Referrers rely on prompt, accurate diagnoses to guide therapy and enable improved patient outcomes. Precise contrast delivery is expected for consistency to allow optimal image quality.
Protocol management and precise contrast delivery
Confidence
- Perform complex CTA and cardiac CT protocols
- Create a tight contrast bolus
- Enable precisely timed contrast delivery
- Individualize contrast dose with Certegra™ P3T™ 2.0
Dual syringe utilization benefits
DualFlow, simultaneous injection of contrast and saline in user-selected ratios can:1
- Enable better visualization of the right heart due to reduction of streak artifacts
- Visualize the right coronary arteries and right ventricles in a single study by achieving more uniform attenuation
Case Reports
DualFlow can provide the ability to perform simultaneous injection of contrast and saline with user-selected ratios with the MEDRAD® Stellant Dual Injection System.

Jensen, CT. NASCI Abstract # 05-A-69-NASCI.
Powered by the MEDRAD® Stellant CT Injection System with Certegra™ Workstation, Certegra™ P3T™ 2.0 calculates individually optimized patient protocols for cardiac CT, pulmonary angiography and abdomen studies.
Standardizing and easing implementation of personalized patient protocols offers important benefits, including:
- Facilitating implementation of multiple CT abdomen protocol strategies
- Reducing occurrences of suboptimal CT pulmonary angiography studies3
Pulmonary Angiography: Certegra™ P3T™ vs. Standard

|
|
Certegra™ P3T™ Weight: 300 pound Contrast: 116 cc Main PA HU: 274 |
Standard Weight: 295 pound Contrast: 80 cc Main PA HU: 171 |
When compared to standard protocols, Certegra™ P3T™ Pulmonary Angiography protocols* result in a higher percentage of exams ranked diagnostic without limitation.4,5
* Albeit at a slightly higher contrast dose than the standard protocol of 80 mL

Scalability
Scalable options address your department’s needs – boost your image
Our customers look for solutions that can keep up with the changing demands of CT imaging at any time.
Take it to the next level
The Radimetrics™ Enterprise Platform seamlessly integrates with your hospital’s IT infrastructure as well as your Bayer smart injection devices, providing the tools to help you achieve both – your contrast and radiation dose management goals.
Certegra™ P3T™ 2.0 Software recommending personalized injection protocols
Personalized patient protocols allow technologists to individualize contrast dose protocols individually at the point of care with ease.
- Abdomen studies
- Pulmonary angiography studies
- Cardiac studies
Certegra™ Imaging System Interface (ISI) – Scanner connectivity
The Certegra™ ISI enables injectors and scanners to communicate, enhancing clinical capability by ensuring appropriate scan timing and simplifying workflow. It enables scanner and injector synchronization. Because multi-slice scanners capture images so quickly, it is critical to have optimal contrast in the area of interest at the precise moment of the scan.
We offer four products:
- Certegra™ ISI 700 (for Philips scanners)
- Certegra™ ISI 800 (for Siemens and Toshiba scanners)
- Certegra™ ISI 900 (for Siemens, Toshiba, Hitachi and General Electric scanners)
- Connect.CT sold as Philips SyncRight (for Philips scanners)
Contrast Dose Management (CDM)
CDM automates documentation of contrast injection at the point of care and throughout the post-procedure workflow.
CDM provides tools to help drive efficiency, reproducible quality and personalized care7:
- Auto-populate contrast injection records transferred to PACS, RIS and Speech Reporting (SR)
- Achieve workflow efficiencies
- Improve reporting accuracy
- Automate documentation
- Use data to inform improvement initiatives
- Accelerate report turnaround time
- Investigate and tie information to outcomes
