摘要

低场磁共振成像(MRI)最近经历了一次复兴,这主要归功于磁共振成像领域取得的众多技术进步,包括优化的脉冲序列、并行接收和压缩传感、改进的定标和重建算法,以及采用机器学习进行图像后处理。对低场磁共振成像的新关注源于传统磁共振成像技术的不普及和对经济实惠的成像技术的需求。低场磁共振成像不依赖于射频屏蔽室、昂贵的液氦和低温淬火管,因此是一种可行的选择。此外,低场磁共振成像的体积和重量相对较小,便于在大多数环境中安装,而且价格适中。低场磁共振成像将为发展中国家和发达国家提供新的成像机会,而不是取代传统的磁共振成像。本文讨论了低场磁共振成像的历史、低场磁共振成像硬件和软件、目前市场上的设备、优缺点以及低场磁共振成像的全球潜力。生物医学工程年度评论》第 26 卷的最终在线出版日期预计为 2024 年 5 月。修订后的预计日期请参见 http://www.annualreviews.org/page/journal/pubdates。

Low-Field, Low-Cost, Point-of-Care Magnetic Resonance Imaging.

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 and reconstruction algorithms, and the adoption of machine learning for image postprocessing. This new attention on low-field MRI originates from a lack of accessibility to traditional MRI and the need for affordable imaging. Low-field MRI provides a viable option due to its lack of reliance on radio-frequency shielding rooms, expensive liquid helium, and cryogen quench pipes. Moreover, its relatively small size and weight allow for easy and affordable installation in most settings. Rather than replacing conventional MRI, low-field MRI will provide new opportunities for imaging both in developing and developed countries. This article discusses the history of low-field MRI, low-field MRI hardware and software, current devices on the market, advantages and disadvantages, and low-field MRI's global potential.
