Helium-Free Magnetic Resonance Imaging: Transforming Magnetic Resonance Imaging through Sustainable Magnet Technology.
Review in Journal of medical physics. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Magnetic resonance imaging (MRI) remains one of the most powerful diagnostic tools in medicine; however, its dependence on liquid helium for superconducting magnet cooling poses substantial economic, environmental, and logistical challenges. The global helium shortage and rising operational costs have accelerated the pursuit of sustainable alternatives that can maintain high diagnostic performance while reducing ecological impact. A systematic literature review was conducted using PubMed, Scopus, ScienceDirect, and Google Scholar databases, covering studies published between 2018 and 2025. The analysis focused on innovations in helium-free and cryogen-minimized MRI systems, including cryocooler-based conduction cooling, high-temperature superconductors (HTS), permanent and resistive magnet technologies, and the integration of artificial intelligence (AI) and digital twin frameworks for performance optimization. Findings indicate that helium-free MRI technologies deliver comparable image quality, field stability, and clinical utility to conventional systems while offering significant reductions in helium dependency, power consumption, and maintenance costs. Cryocooler and HTS-based magnets enable higher operational efficiency and reliability, while portable low-field permanent magnet systems enhance accessibility in low-resource settings. Moreover, AI-driven image reconstruction and predictive maintenance via digital twins improve workflow efficiency and sustainability. Helium-free MRI represents a paradigm shift toward sustainable and equitable medical imaging. By combining advanced magnet technologies, intelligent optimization systems, and eco-efficient design, these next-generation scanners address the global helium crisis and environmental footprint of healthcare infrastructure, redefining MRI as a cornerstone of green radiology.
