Low-Field MRI Under 1T Now Viable for Neuroimaging, Boosted by AI and Novel Hardware

Modern low-field MRI (<1T) now yields diagnostic-quality neuroimages, enabled by AI reconstruction and improved gradient design. Reduced susceptibility artifact aids skull base and implant imaging, while portability permits point-of-care scanning. However, high-field MRI remains…

• Review of technological advances in low-field MRI, including AI-assisted reconstruction, optimized pulse sequences, and improved gradient performance.
• Key clinical advantages include reduced susceptibility artifacts near skull base/implants, markedly lower SAR and acoustic noise, and potential for point-of-care and intraoperative use.
• Primary limitations remain lower signal-to-noise ratio (SNR) and limited spatial resolution compared to high-field systems.
