Accutron® MR3

Cardiac Stress

Accutron® MR3 is a dual head dual syringe contrast media injector with a third syringe unit operating as a dedicated infusion pump specifically indicated for MR Stress test imaging. An MR stress test is a chemical induced stress imaging examination of the heart using a pharmaceutical agent such as Adenosine or Dobutamine.

These agents simulate the effects of exercise in patients thereby causing the coronary arteries to dilate. This dilation with contrast media allows the visualization of the heart muscle not receiving enough blood supply i.e., ischemia. In addition, Accutron® MR3 software features MPRO Assist which helps guide you during setup for the optimal injection and infusion rates.

Guided Assistance

Patient based profile assistant (MPRO) generates the optimal injection and infusion protocol based upon established criteria helping you to be more efficient in your daily workflow.

Infusion Pump

The integrated infusion pump provides for continuous infusion of diagnostic medication during an MR scan. It also features bolus functionality and is ideal for MRI Stress testing

Remote Control

Offers a comprehensive view to monitor the medication infusion and contrast injection phases. It also provides complete remote operational control including parameter adjustment and injection from the scanner control room.

Focus with Accutron® MR & MR3.

Pediatric MR

Pediatric MR imaging faces complex challenges such as minimal flow rate requirements, extremely fragile veins as well as optimal contrast volume selection and delivery.

Accutron® MR & MR3 are both ideal for pediatric imaging because they provide precise injection volume and flow rates with decimal increments allowing for careful administration of the contrast media dose.

It is especially critical in pediatric MR imaging where precise comparability with high quality imaging is needed, such as in pediatric cardiac and oncologic imaging.

MR Mammography

Contrast media perfusion in MR breast imaging requires a high degree of precision coupled with an extremely high necessity for imaging reproducibility. It allows conspicuous lesions with premature and higher grade enhancements to be analyzed. Only a power injector can meet this requirement in earnest.

MR Neuro

Complex vascular changes can be easily visualized via the adjustment of injection parameters on the power injector. As an example, MR stroke imaging requires clearly defined contrast media injection profiles, as they are essential in enabling evaluation of contrast media distribution throughout the brain.

MR Angiography

Using the dual injection head of Accutron® MR and MR3 for multiple phase protocols allows you to optimize the delivery of contrast for vascular dynamic studies.

This includes flushing the arterial supply with saline to ensure a compact bolus is delivered. It also allows subsequent examinations to be later reproduced with the same protocol.

By simultaneously injecting contrast media and saline solution, it allows for the bolus geometry and peak enhancement to be adjusted as needed when focusing on organ tissue enhancement. For example, to increase the duration of the contrast peak for larger vessel studies.

Should I use a power injector?

Using power injection is inherently more stable and repeatable with respect to flow rate, timing and duration of injection during a patient examination.

A power injector such as Accutron® MR or Accutron® MR3 makes the quality of imaging more predictable, which ultimately enhances the procedural safety for the patient.

Unfortunately, hand injections are not suitable for repeatability as the variability of flow rate, time and duration are not easily controlled and/or maintained due to the manual variabilities introduced.
