Taylor Kimberly","Edmond Knopp","Chip Truwit","Khan Siddiqui","S. Ather Enam"],"abstract":"Background: Ultra-low-field magnetic resonance imaging (ULF-MRI) has emerged as an alternative with several portable clinical applications. This review aims to comprehensively explore its applications, potential limitations, technological advancements, and expert recommendations. Methods: A review of the literature was conducted across medical databases to identify relevant studies. Articles on clinical usage of ULF-MRI were included, and data regarding applications, limitations, and advancements were extracted. A total of 25 articles were included for qualitative analysis. Results: The review reveals ULF-MRI efficacy in intensive care settings and intraoperatively. Technological strides are evident through innovative reconstruction techniques and integration with machine learning approaches. Additional advantages include features such as portability, cost-effectiveness, reduced power requirements, and improved patient comfort. However, alongside these strengths, certain limitations of ULF-MRI were identified, including low signal-to-noise ratio, limited resolution and length of scanning sequences, as well as variety and absence of regulatory-approved contrast-enhanced imaging. Recommendations from experts emphasize optimizing imaging quality, including addressing signal-to-noise ratio (SNR) and resolution, decreasing the length of scan time, and expanding point-of-care magnetic resonance imaging availability. Conclusion: This review summarizes the potential of ULF-MRI. The technology’s adaptability in intensive care unit settings and its diverse clinical and surgical applications, while accounting for SNR and resolution limitations, highlight its significance, especially in resource-limited settings. Technological advancements, alongside expert recommendations, pave the way for refining and expanding ULF-MRI’s utility. However, adequate training is crucial for widespread utilization.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/9ecb8882-3cf9-449d-9ff6-ffae80ff3c8c/featured/hero-1781559432802.png","publishDate":"2024-06-28T00:00:00.000Z","doi":"10.25259/SNI_162_2024","categories":["General Neurosurgery","Review Article"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2024/06/12968/SNI-15-218.pdf"}
