Conventional high-field MRI scanners make it challenging to examine body regions containing metallic implants. The large difference in magnetic susceptibility between metal and the surrounding tissue causes significant local magnetic field distortion, leading to the familiar image artifacts around implants.
Even with advanced techniques such as WARP and SEMAC, image quality on conventional 1.5T and 3T MRI systems remains limited, making accurate diagnosis difficult.
At a lower field strength of 0.55T, the systems of the MAGNETOM Free. Platform have the advantage of producing significantly fewer susceptibility artifacts than high-field systems.
With far fewer distortions and artifacts near implants, these lower-field scanners enable better visualization of pathologies, despite the lower resolution and signal-to-noise ratio.
As in high-field imaging, these examinations use turbo spin echo (TSE) sequences with optimized acquisition parameters that are activated via the WARP option. Increased excitation and readout bandwidths are crucial here, especially in combination with STIR technology as a robust alternative to conventional spectral fat saturation for fat suppression.
In addition to established advanced acceleration techniques (parallel imaging and Simultaneous Multi-Slice acquisition), deep-learning-based image reconstruction methods offer enormous potential also at lower field strengths. Enabling high-quality diagnostic MR images in very acceptable acquisition times on 0.55T systems.

DANTE Pulse Changed Our Clinical Routine and Research by Yasutaka Fushimi, MD, PhD; et al. (Department of Diagnostic Imaging and Nuclear Medicine, Graduate School of Medicine, Kyoto University, Kyoto, Japan)
Vessel wall MRI (VW-MRI) has become an essential tool for characterizing pathological features of the vessel wall in clinical practice. Its clinical importance is well established in evaluating atherosclerotic disease, both extracranially and intracranially.
With the introduction of additive pre-pulses such as motion-sensitized driven equilibrium (MSDE) and delay alternating with nutation for tailored excitation (DANTE), VW-MRI has expanded its potential applications beyond atherosclerosis and has improved the assessment of atherosclerotic lesions.
While MSDE is widely used, its low diffusion-sensitizing capability can cause blurring and T2-weighted effects.
In contrast, the DANTE pulse attenuates signals from flowing spins by applying a train of low flip-angle pulses along the flow direction, resulting in less attenuation of signals from static tissue.
The authors have encountered various clinical cases in which non-contrast and contrast-enhanced DANTE T1-SPACE imaging helped visualize abnormal findings. This review presents representative cases acquired on a 3T scanner, illustrating the clinical utility of DANTE T1-SPACE imaging.

Postmortem computed tomography (PMCT) is well established for medicolegal death investigation. However, certain limitations of PMCT can be overcome with postmortem magnetic resonance imaging (PMMRI) especially in the brain, spinal cord, and heart, and in young children.
Postmortem imaging uses all the CT and MRI techniques available in clinical radiology, albeit with adjustments to allow for changes in the body after death and refrigeration.
The authors present a case of hypoxic ischemic brain injury, where both PMCT and PMMRI provided information about the deceased. This included iodine leak into the basal ganglia following high-dose antemortem CT scanning confirmed on dual energy PMCT, and swelling and T2 hyperintensity in gray matter of the basal ganglia and cortex on PMMRI.
These findings were confirmed as hypoxic ischemic encephalopathy at autopsy examination.

Thanks to technological advances, many implantable devices such as ICDs are now designed to be MR compatible, enabling wider clinical use of cardiac MRI in this patient population.
However, the presence of ferromagnetic materials in the generator of these devices creates strong field inhomogeneities around the device. This results in bright-blood LGE images and black-blood LGE images that are heavily impacted by signal loss, hyperintensity artifacts, and image distortion, often resulting in non-diagnostic images.
The authors present the “wideband” MRI technique for reducing ICD-related artifacts, and its application to black-blood LGE imaging.

Undersampled 3D whole-heart inversion recovery (IR) Dixon gradient echo (GRE) accelerated by variable-density spiral-like Cartesian trajectory (VD-CASPR) with image-based navigators (iNAVs) for motion estimation and nonrigid motion-corrected iterative sensitivity-encoding (SENSE) reconstruction with 100% respiratory scan efficiency has the potential for integration into workflows for left atrial and left ventricular delayed enhancement.
For the majority of patients, 3D non-contrast-enhanced T2-prepared balanced steady-state free precession (bSSFP) provides highly diagnostic image quality. However, iNAV CE-MRA has several key advantages that warrant consideration for use. These include a lack of dependency on chemically selective fat saturation preparatory pulses, which may inadvertently saturate the water signal in the aortic arch and proximal descending aorta; and demonstrably superior blood pool signal uniformity, allowing performance consistency of threshold-based anatomical segmentation used to generate centerline semi-automated aortic measurements (CSAMs). iNAV CE-MRA can also be combined with time-resolved angiography with interleaved stochastic trajectories (TWIST) for comprehensive dynamic 4D angiography.
Given the rapidly shifting landscape of modern MR imaging, referral patterns, provider needs, and the increase in patient complexity, it is also increasingly important to have techniques that are robust to susceptibility artifacts from sources such as internal cardiac defibrillators (ICDs)/pacemakers, thoracic endovascular aortic repairs (TEVAR), and hybrid aortic repairs.

Abbreviated Breast MR Protocol at the Radboud University Medical Center
by Professor Ritse Mann and Lejla Kočo (Radboudumc Nijmegen, The Netherlands / Netherlands Cancer Institute (Antoni van Leeuwenhoek), Amsterdam, The Netherlands).
At the Radboud University Medical Center, different MRI protocols are used for breast imaging depending on the purpose.
- 🕒 ~ 20-minute MRI protocol for diagnostic imaging
- ⏱️ ~ 8-minute abbreviated MRI (abMRI) protocol for screening
The motivation to implement abbreviated breast MR imaging (abMRI) at the Radboud was to increase cost-effectiveness.
The idea was to be able to scan more women within the same timeframe with MRI. This would therefore allow greater access to MRI screening to more women and reduce the time women had to spend inside the MRI scanner (anxiety, claustrophobia, lying still).
With the abbreviated MRI protocol three patients can be scanned per hour. If DWI is omitted, it is also possible to scan four patients in one hour.
Another important benefit is that the MRI scanner is almost continuously in use.

The Spectrum of Interventional MRI by David Woodrum, M.D., Ph.D.; Setayesh Sotoudehnia, M.D.; and Scott Thompson, M.D., Ph.D. (Mayo Clinic, Rochester, MN, USA).
Clinical use of magnetic resonance imaging (MRI) for image-guided procedures began in the late 1980s. However, early procedures were limited by tools, in-bore access to the patient, and MR imaging limitations.
Interventional MRI (iMRI) offers some natural advantages including superior soft tissue resolution, ease of multiplanar imaging, lack of ionizing radiation, and the ability to re-image the same slice.
MRI guidance is particularly advantageous when the pathology can be best or only visualized with MRI. There has been tremendous growth in clinical applications and positive patient outcomes of iMRI over the past three decades, and the community has benefited from close collaboration between interventional radiologists, MR physicists, and MR nurses.
The figure shows summary images from the MRI-guided TULSA treatment.

First Experiences with MAGNETOM Flow for Veterinary Practice by Lizzy Wilson, PgD, BSc (hons), HCPC (Lumbry Park Veterinary Specialists, Alton, UK).
When it came time to replace their MRI system, the team at Lumbry Park Veterinary Specialists selected the 1.5T MAGNETOM Flow, notably for its DryCool technology, which uses just 0.7 liters of liquid helium.
The system’s sealed-for-life magnet design eliminates the need for helium refills. Since helium is a finite resource, this makes the system more environmentally sustainable.
The integration of AI-assisted imaging with Deep Resolve significantly improves image quality, especially for smaller patients under 5 kg.
The new BioMatrix Contour Coils provided with the scanner are particularly well-suited to veterinary applications. They are flexible and soft, enabling close contact with the animal, which enhances signal quality.
While initial protocol development posed a challenge, the optimized protocols are now available on the MAGNETOM World site to benefit other veterinary practices.

As MRI-guided interventions become more viable with advances in real-time imaging and in low- and midfield systems, there is a growing need for accessible, hands-on training tools that build operator confidence and procedural accuracy.
Located in West Lafayette, Indiana, USA, a 0.55T MAGNETOM Free.Max system has been fitted to meet the needs of a preclinical, investigational setting. Four MRI display monitors (NordicNeuroLab, Bergen, Norway) on MR-conditional boom arms allow for visualization of images.
An MR-conditional wireless headset system enables continuous communication between the MRI technologist at the helm and the interventionalist and staff in the MR room even during imaging.
In any procedure, the technologist is responsible for the safety of the patient and the personnel in the magnet room. It can be a daunting task, and one of the main components of any successful venture is communication.
In traditional X-ray imaging, users warn others about “X-ray!”; CT systems display warning lights that read “CT in use”; and during live X-ray imaging, interventionalists call for “fluoro”.
The language of interventional MRI (iMRI) is still evolving, but it should be clear and consistent. The authors describe their collaborative efforts to establish a unique, agreed-upon language that assists in successful communication – an iMRI language that helps to streamline procedures while maintaining safety for all involved.

Arterial Spin Labeling (ASL) is an MRI technique that uses the water in arterial blood as an endogenous contrast agent to non-invasively evaluate perfusion. ASL is available as a 2D EPI sequence (ASL 2D) and as a 3D GRASE sequence (ASL 3D).
Both ASL 2D and ASL 3D include a separate M0 scan and an inline calculation of relative cerebral blood flow (relCBF) maps for a quantitative evaluation of perfusion.
ASL 3D can be run with a single TI or multiple TI's. The latter are used for fitting the Buxton model to the inflow curve, providing both relCBF and bolus arrival time BAT maps.
Clinical applications of ASL include:
- Evaluation of brain tumors
- Neurodegenerative diseases such as Alzheimer’s and frontotemporal dementia
- Acute stroke and evaluation of Transient Ischemic Cerebral Attack (TIA)
- Chronic cerebrovascular disease
- Functional evaluation of the brain using BOLD techniques
- Pre-interventional planning

MRI-Guided Thermal Ablation in Urologic Oncology: The Nijmegen Experience
By Jurgen J. Fütterer, PhD; et al. (Department of Medical Imaging, Radboudumc, Nijmegen, The Netherlands).
Interventional magnetic resonance imaging (iMRI) has expanded the possibilities for interventional treatments and is becoming an essential tool for image-guided therapies in urologic oncology. Unlike ultrasound (US) or computed tomography (CT), MRI provides high-resolution images and excellent soft tissue contrast for prostate and kidney lesions, aiding in precise tumor localization and distinct tumor border identification. This capability supports real-time targeting of lesions while safeguarding adjacent critical structures.
Additionally, MRI permits ongoing monitoring and management of the treatment process, including mapping tissue temperatures during thermal therapies. Notably, it does not involve ionizing radiation, which is particularly important for younger patients and for cases requiring several interventions
At Radboud University Medical Center (Radboudumc), MRI-guided prostate treatments began in 2011, followed by the first MRI-guided kidney treatment in 2012. These procedures are performed using a dedicated wide-bore 3T MRI system (MAGNETOM Skyra) in a sterile operating room environment.
In this article, the authors share their experience with various MRI-guided prostate treatments, including:
- Cryoablation
- Focal laser ablation
- Transurethral ultrasound ablation (TULSA)
- MRI-guided cryoablation of renal tumors.

Establishing an MRI-Guided Intervention Service Using a 0.55T System: Initial Experiences and Workflow Development
By Jan Robert Kroeger, M.D.; et al. (Department of Radiology, Neuroradiology and Nuclear Medicine, Johannes Wesling Klinikum Minden, University Hospital of Ruhr-Universität Bochum, Germany).
Interventional radiology plays a crucial role in modern diagnostics and therapeutics. While computed tomography (CT) and ultrasound (US) guidance are well established for percutaneous needle-based procedures, certain clinical scenarios present challenges.
The radiology department at Johannes Wesling Klinikum Minden has a robust program for CT-guided interventions, performing approximately 700 procedures annually, including biopsies, drainages, ablations, and pain management injections.
Despite this experience, specific limitations were identified that prompted improvements.
In some cases, lesions that were clearly visible on diagnostic #MRI were poorly or not visualized under CT guidance, hindering successful biopsy.
Additionally, concerns were raised regarding cumulative radiation exposure, particularly in younger patients undergoing procedures like injection therapy for back pain, highlighted the need for non-ionizing imaging alternatives.
MRI guidance offers potential solutions by providing superior soft tissue contrast without ionizing radiation.
As a result, an MRI-guided intervention service was established “de novo”.
This manuscript presents the initial experiences, challenges encountered, workflow development, and key learnings during the implementation phase using a 0.55T MAGNETOM Free.Max system.

Liver cancer is one of the fastest-growing cancers and a major contributor to cancer-related mortality. Minimally invasive, nonsurgical local liver therapies play a key role in appropriately selected patients with hepatobiliary cancer.
Magnetic resonance imaging (MRI) offers a compelling solution for liver interventions by providing multiplanar, real-time needle guidance without exposure to ionizing radiation.
It has excellent soft tissue contrast, outstanding spatial and temporal resolution, and functional imaging capabilities like diffusion-weighted imaging. Additionally, real-time temperature measurement during liver ablation helps to ensure complete tumor destruction while preserving surrounding healthy tissue and thus minimizing collateral damage
The integration of MRI guidance into hepatobiliary cancer diagnosis and treatment marks a significant advancement in interventional oncology. Its unique qualities enhance precise and safe planning, execution and monitoring of liver biopsies, liver tumor ablation, and percutaneous biliary drainage.
