【摘要】 脑磁图（magnetoencephalography,MEG）作为无创脑功能成像技术，在儿科神经系统疾病诊疗中发挥着越来越重要的作用。近年来，基于光泵原子磁力计（optical pumped magnetometer,OPM）技术的无液氦脑磁图（OPM-MEG）为儿童脑科学研究与脑疾病精准诊疗提供了全新工具。本文就儿童OPM-MEG的技术原理、临床应用标准、检测规范及报告要求展开论述，旨在建立科学、规范的标准化操作流程，推动该技术在儿科领域的合理应用与发展。内容涵盖设备核心参数、适应症与禁忌证、检测前准备、操作流程优化、数据质量控制及报告规范等关键环节，为开展儿童OPM-MEG检测提供全面指导。更多还原

【Abstract】 Magnetoencephalography(MEG), as a non-invasive brain functional imaging technology, plays an increasingly important role in the diagnosis and treatment of pediatric neurological disorders. In recent years, the emergence of helium-free MEG based on optical pumped magnetometer(OPM) technology(OPM-MEG) has provided a novel tool for pediatric brain research and precise diagnosis and treatment of brain diseases. This article elaborates on the technical principles, clinical application standards, testing protocols, and reporting requirements for pediatric OPM-MEG,aiming to establish a scientific and standardized operational framework to promote its rational application and development in pediatric practice. The content covers key aspects such as core equipment parameters, indications and contraindications, pre-examination preparations, optimized operational workflows, data quality control, and reporting standards, offering comprehensive guidance for conducting pediatric OPM-MEG examinations.更多还原
