Siemens Healthineers Unveils Magnetom Free.XL: Expanding the Role of Interventional MRI

At RSNA 2025, Siemens Healthineers introduced the Magnetom Free.XL¹, a 0.55T MRI system designed to meet the growing demands of interventional radiology. As the centerpiece of a new integrated iMRI suite, Magnetom Free.XL brings real-time, radiation-free imaging into minimally invasive procedures—where soft tissue visualization and operator access are paramount.

“Our goal is to elevate health globally by supporting healthcare providers in efficiently delivering high-quality, patient-centered care,” said Andreas Schneck, head of Magnetic Resonance at Siemens Healthineers. “Magnetom Free.XL is designed to unlock the full potential of MR in the interventional suite, expanding the imaging toolbox by matching the right modality to the right patient at the right time.”

The scanner operates using Siemens’ DryCool technology³, which eliminates the need for helium and a quench pipe. This simplifies installation and allows for greater flexibility in constrained clinical environments. With its extra-wide 100 cm flared bore and an optional lifted magnet, the system is engineered for improved operator access and enhanced ergonomics. According to the company, early ergonomic studies suggest these features may support endurance and reduce fatigue for interventionalists during extended procedures⁶.

Magnetom Free.XL also continues Siemens Healthineers’ work at 0.55T—a field strength introduced in 2021 that helps improve the visibility of interventional devices, reduce metal artifacts⁴, and limit heating effects during procedures⁵.

Designed for versatility, the system supports a full range of diagnostic applications in addition to interventions. The inclusion of XL gradients and Deep Resolve, the company’s AI-powered image reconstruction engine, brings high-resolution soft tissue imaging and real-time MR capabilities into the interventional setting. Cardiac imaging at 0.55T is also expected to enter clinical routine for the first time with Magnetom Free.XL¹.

To support MR-guided needle procedures, the system integrates with the myNeedle Companion software¹, offering 3D path planning, skin entry-point marking, and real-time navigation. A complete coil portfolio—featuring form-adaptive contour coils and interventional⁷ coils—supports imaging across a broad patient population, including pediatric, bariatric, claustrophobic, and pregnant patients.

“Magnetom Free.XL is poised to become a cornerstone of personalized treatment, not only for interventions, but also in diagnostic scenarios, such as for pediatric, bariatric, claustrophobic or pregnant patients,” said Professor Afshin Gangi, M.D., from University Hospital Strasbourg, France. “The open and ergonomic design supports comfortable patient access and helps to stay focused – even during long or back-to-back procedures.”

The system will also be the core of a new interventional MRI suite developed in collaboration with Cook Medical. The partnership aims to integrate Siemens’ imaging innovation with Cook Medical’s expertise in device design and procedural education⁷.

To ensure seamless movement between diagnostic, intraoperative, and interventional settings, the suite features the Nexaris Dockable Table. With its ability to accommodate both routine and complex procedures, the Magnetom Free.XL is positioned as a flexible and high-performing solution for modern radiology departments.

By bringing MRI into the interventional suite—alongside Siemens’ existing portfolio of CT, angiography, mammography, ultrasound, and interventional oncology tools—the company envisions a future of deeply integrated, image-guided therapies that elevate both precision and patient care.
