A Brief History of the Development of Low-Field Magnetic Resonance Imaging Systems and Their Applications and Prospects in Neurological Diseases
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.
