Background: Magnetic Resonance Imaging (MRI) is an essential diagnostic modality, but conventional superconducting MRI systems rely on liquid helium for magnet cooling. Helium shortages, rising costs, and environmental concerns have accelerated interest in helium-free MRI technologies.
Aim: To review current advancements, clinical applications, benefits, and challenges associated with helium-free MRI systems.
Methods: A narrative review of literature from 2010 to 2025 was conducted using databases such as PubMed, Scopus, and Google Scholar. Key terms included “helium-free MRI”, “cryogen-free MRI”, “high-temperature superconductors”, “permanent magnet MRI”, and “low-field MRI”.
Results: Helium-free MRI can be achieved through cryogen-free superconducting magnets, permanent magnets, and low-field systems. These technologies offer reduced operational costs, simplified maintenance, and greater accessibility in resource-limited settings. However, limitations include reduced signal-to-noise ratio (SNR), lower image resolution in some systems, and technical challenges in magnet design.
Conclusion: Helium-free MRI represents a promising evolution toward sustainable imaging. Future developments in high-temperature superconductors, improved coil technology, and AI-driven reconstruction methods are likely to enhance clinical utility and broaden adoption.
