摘要

磁共振成像（MRI）扫描仪的磁场强度越高，通常越能在更短时间内获得更高的信噪比与图像分辨率。然而，高场强 MRI 设备存在购置成本高昂、安装要求严苛、维护费用不菲等问题，使其难以广泛普及。相比之下，低场强 MRI 扫描仪因成本较低且具备便携性，已逐步应用于临床及相关科研工作。本文旨在综述低场强 MRI 扫描仪当前在儿科神经系统疾病、新生儿监护室及产前胎儿疾病中的诊断价值，并对其应用前景进行展望，以期全面阐释低场强 MRI 在胎儿及儿科诊断领域的应用价值与发展前景。

Abstract

Generally, the higher the magnetic field strength of a magnetic resonance imaging (MRI) scanner, the greater the likelihood of achieving a higher signal-to-noise ratio and improved image resolution within a shorter scanning time. However, high-field-strength MRI systems are associated with significant limitations, including high acquisition costs, stringent installation requirements, and substantial maintenance expenditures, which collectively hinder their widespread adoption. In contrast, low-field-strength MRI scanners, due to their relatively lower costs and enhanced portability, have increasingly been integrated into clinical practice and related research settings. This review aims to summarize the current diagnostic applications of low-field-strength MRI in pediatric neurological disorders, neonatal intensive care, and prenatal fetal imaging, while also discussing their future potential. This article seeks to provide a comprehensive overview of the clinical value and developmental trajectory of low-field-strength MRI in fetal and pediatric diagnosis.
