Siemens Healthineers introduces Magnetom Flow MRI with improved sustainability, efficiency

At this year’s European Congress of Radiology (ECR) in Vienna, Siemens Healthineers introduced the Magnetom Flow, which is still under development and not yet commercially available. It is the first 1.5 tesla platform for magnetic resonance imaging with a closed helium circuit and no quench pipe. The amount of liquid helium required for cooling has been reduced to 0.7 litres from as much as 1,500 litres thanks to the Dry Cool technology, bringing down costs and saving resources. The quench pipe was previously needed to safely allow cold helium to escape from the building directly into the atmosphere in the event of an emergency shutdown.

The new system with a bore size of 60 cm covers the entire range of applications for MRI. Comprehensive use of image reconstruction based on artificial intelligence enables shorter measurement times with improved image quality. Magnetom Flow’s high degree of automation simplifies the complex MRI workflow to ensure the highest quality independently of user experience and increases efficiency.

Magnetom Flow is the second virtually helium-free MRI platform from Siemens Healthineers with Dry Cool technology. The company has set itself the goal of making an important contribution to greater sustainability in the healthcare sector in the coming years with this and other technologies.

“The world’s population is growing and with it the need for MRI exams. However, the simultaneous rise in cost pressure and lack of personnel make it difficult to operate MRI economically,” said Andreas Schneck, head of Magnetic Resonance at Siemens Healthineers. “The Magnetom Flow platform provides the answer to the challenges facing healthcare systems. It increases productivity in routine clinical practice due to its high degree of automation and makes a decisive contribution to sustainability with the Dry Cool technology.”

As well as using significantly fewer natural resources such as helium, Magnetom Flow considerably reduces energy consumption. With the help of the improved Eco Gradient Mode, the system automatically switches off energy-intensive components when they are not needed. With the introduction of Eco Power Mode in combination with heliumfree technology, it is possible to save a further 30 percent in cooling capacity overnight. This makes Magnetom Flow one of the most sustainable MRI platforms from Siemens Healthineers. Compared to many other 1.5T scanners, Magnetom Flow reduces installation requirements and costs due to its compact size of less than 2 metres in height, 24 square metres in footprint and the lack of a quench pipe.

In clinical practice, Magnetom Flow can significantly reduce patient slot times and improve the patient experience thanks to its intuitive and highly automated design. The entire operation can now be carried out next to the patient – from registration to positioning to starting the examination. This saves time and can give patients peace of mind. In addition, the coils, which flexibly adapt to the body like a blanket, feature novel sensors to enable automatic position detection in the exam room. To keep examination times short and improve image quality, the system is equipped with extensive AI-supported image reconstruction. In combination with simplified workflows, overall patient throughput can be increased significantly.
