摘要/Abstract

摘要： 近10年来，高场强MRI系统在医学领域的应用和研究不断深入，但其安装和扫描条件要求较高，运行成本昂贵，限制了其在基层医院的普及。相比之下，低场强（0.01～1.0 T）MRI虽然成本较低，但因其成像性能欠佳，也未能在临床实践中发挥更大的作用。随着技术的不断发展，目前低场强MRI有望实现类似于高场强MRI系统的各种应用，通过优化软件、硬件设计和技术革新，低场强MRI可以在保持成本经济、便于转运优势的同时提高信噪比，达到提高诊断性能，更广泛地应用于临床实际场景的目标。特别是在急重症诊断方面，低场强MRI有望成为脑血管疾病诊断和监测的重要工具之一。本文追溯了低场强MRI的发展历程，对其在神经系统疾病临床应用中的进展进行了综述，旨在为未来低场强MRI技术的发展探寻方向。

Abstract: In the past decade, the application and research of high-field MRI systems has deepened in the medical field. However, its installation and operating conditions are demanding, and its running cost is high, which limits its popularity in grassroots hospitals. In contrast, low-field (0.01-1.0 T) MRI, although relatively cheaper, has not been effective in clinical practice due to its poor performance. With the continuous development of technology, low-field MRI is now expected to achieve various applications similar to high-field MRI systems. Through software optimization, hardware design, and technical innovation, low-field MRI can improve the signal-to-noise ratio while maintaining the advantages of cost economy and easy transport, improve diagnostic performance, and be more widely used in practical clinical scenarios. Especially in critical illness diagnosis, low-field MRI is expected to become one of the important tools for the diagnosis and monitoring of cerebrovascular diseases. This paper reviewed the development of low-field MRI and its clinical application in neurological diseases, aiming to explore the future development direction of low-field MRI technology.
