Imaging Titanium and Carbon Fiber Spinal Implants at 0.55T, 1.5T, and 3T #MRI: A Phantom Experiment by Xin Miao, Ph.D. et al.

The authors investigated the imaging of titanium vs. Carbon/PEEK pedicle screws at 0.55T, 1.5T, and 3T, with and without advanced metal artifact reduction techniques. Their findings demonstrate that techniques such as WARP and SEMAC effectively reduce metal artifacts near titanium implants at all three field strengths. In contrast, Carbon/PEEK screws could be imaged using standard #MRI protocols without implant-related image artifact. It is essential to acknowledge that there are numerous considerations involved in imaging with metal implants. Metal artifact reduction strategies often come at the cost of reduced SNR, increased scan times, and higher SAR. Imaging at lower field strengths (e.g., 0.55T) and with non-metal hardware may dramatically simplify protocol development in such scenarios. Beyond excellent soft-tissue contrast, MRI techniques like diffusion-weighted imaging (DWI) and magnetic resonance spectroscopy (MRS) offer valuable functional information that aids in assessing tissue viability, identifying areas of hypoxia, and optimizing dose delivery based on tumor biology. Furthermore, MRI can facilitate monitoring of tumor response and treatment efficacy during and after radiation therapy without concerns over ionizing radiation exposure. This capability empowers clinicians to evaluate treatment response and adapt treatment plans as needed. Whether in treatment planning, functional imaging, or treatment follow-up, addressing the challenge of imaging with spine implants requires close collaboration between radiation oncologists, medical physicists, and radiologists. Optimization of MRI protocols, development of artifact reduction strategies, and accurate integration of MRI data into the treatment planning process are paramount. Despite these challenges, the benefits of using MRI in spine radiation therapy should outweigh the limitations, and ultimately lead to improved treatment outcomes for patients with spinal tumors.

MRI-Guided Planning for Pelvic Brachytherapy By Florian Putz, M.D. (Department of Radiation Oncology, Universitätsklinikum Erlangen, FAU Erlangen-Nürnberg, Erlangen, Germany) At University Hospital Erlangen, Germany, MRI plays a central role in the planning of pelvic brachytherapy. After applicator implantation, a planning MRI is performed on the 1.5T MAGNETOM Sola RT Pro Edition, which is conveniently located within the radiation oncology department. This setup enables streamlined workflow between the procedure area and the HDR treatment rooms. The MR-in-RT working group at University Hospital Erlangen shares their MRI protocols for pelvic brachytherapy. Developed in accordance with the GEC-ESTRO recommendations, these protocols include 3D sequences such as T2-SPACE and T1-VIBE Dixon. Together, they provide excellent visualization of the target volume, organs at risk, and applicators, supporting accurate and reproducible treatment planning.

Stereotactic Radiotherapy Cranial Protocol by Simon Atkins, BAppSc (Hons), MSc, DipIPEM(S), CMPS, and MACPSEM (ICON Cancer Centre Australia). The goal was to establish a unified imaging protocol across ICON centers, ensuring consistency while remaining feasible across different baseline systems (syngo MR XA30, XA50, and XA60). A key objective was to create a workflow that could be implemented with minimal radiotherapy-specific expertise required from on-site radiographers. Physician requirements focused on achieving 1 mm isotropic 3D imaging for SRS treatments. In response, T1 SPACE and T2 SPACE sequences were prioritized due to their superior spatial resolution and high-quality three-dimensional datasets compared with conventional T1 MPRAGE and T2 TSE acquisitions. The MPRAGE and T2 TSE sequences were retained as optional components to accommodate site-specific preferences. To support consistent implementation across sites, the protocol also includes guidance images and explanatory notes to assist radiographers during planning, with particular emphasis on maintaining critical parameters and avoiding unintended modifications.

SRS requires very high precision for the delineation of the target and OARs, and for patient setup in order to ensure accurate treatment delivery. For contouring, it is essential to have high-quality images that provide high spatial resolution over the full brain and superior soft tissue contrast to be able to distinguish the soft tissue structures within the brain. For this reason, MRI is the standard for target volume and OAR contouring for SRT. This study shows that the 0.55T MAGNETOM Free.Max RT Edition can produce #MRI datasets suitable for the demanding requirements of SRT planning. Through careful sequence selection and optimization, adequate SNR and spatial resolution were achieved for precise target and OAR delineation. While individual sequence scan times on the 0.55T system are moderately longer than those typically achieved on 1.5T or 3T scanners, total clinical protocol time remained under 30 minutes, which is well-tolerated by patients and integrates efficiently into the clinical radiotherapy workflow. The successful identification of a very small, previously uncertain metastatic lesion underscores that the image quality is not only adequate but clinically robust for identifying small targets that are critical in SRT. The viability of using a 0.55T system for MR simulation in SRT has significant implications. It potentially broadens access to high-quality MR simulation for radiotherapy centers that may not have access to high-field MR systems due to the cost or siting constraints associated with higher field strengths. Furthermore, the specific design characteristics of the MAGNETOM Free.Max RT Edition (e.g., its 80 cm bore) offer benefits for patient comfort and setup. This work shows that despite the inherently lower SNR of low-field MRI, optimization strategies can yield clinically excellent results for advanced applications like SRT.
