Low-field magnetic resonance imaging (MRI) has recently experienced a renaissance that is largely attributable to the numerous technological advancements made in MRI, including optimized pulse sequences, parallel receive and compressed sensing, improved calibrations reconstruction algorithms, adoption of machine learning for image postprocessing. This new attention on low-field MRI originates from lack accessibility traditional need affordable imaging. provides viable option due its reliance radio-frequency shielding rooms, expensive liquid helium, cryogen quench pipes. Moreover, relatively small size weight allow easy installation most settings. Rather than replacing conventional will provide opportunities both developing developed countries. article discusses history hardware software, current devices market, advantages disadvantages, MRI's global potential.
