磁共振成像（MRI）与其他放射成像模式相比具有优越的上级软组织对比度，其生理和功能应用已导致全球MRI扫描的显著增加。因此，必须进行全面的MRI安全培训，以保护患者和其他医护人员免受MRI套件中磁场的潜在生物效应和风险。对于将在MRI环境中工作或转诊患者进行MRI扫描的所有医疗保健专业人员来说，了解MRI套件中安全区的目的以及MRI适当性标准非常重要。本文旨在概述当前的磁共振安全指南，并讨论MRI套件中磁场的安全风险，包括铁磁物体的力和扭矩、组织加热、外周神经刺激和听力损伤。还将讨论植入器械的MRI安全性和兼容性、妊娠期间的MRI扫描和MRI造影剂的潜在风险，并将提供全面的MRI安全培训，以避免MRI套件中的致命事故。
Magnetic Resonance Imaging (MRI) has a superior soft-tissue contrast compared to other radiological imaging modalities and its physiological and functional applications have led to a significant increase in MRI scans worldwide. A comprehensive MRI safety training to protect patients and other healthcare workers from potential bio-effects and risks of the magnetic fields in an MRI suite is therefore essential. The knowledge of the purpose of safety zones in an MRI suite as well as MRI appropriateness criteria is important for all healthcare professionals who will work in the MRI environment or refer patients for MRI scans. The purpose of this article is to give an overview of current magnetic resonance safety guidelines and discuss the safety risks of magnetic fields in an MRI suite including forces and torque of ferromagnetic objects, tissue heating, peripheral nerve stimulation and hearing damages. MRI safety and compatibility of implanted devices, MRI scans during pregnancy and the potential risks of MRI contrast agents will also be discussed and a comprehensive MRI safety training to avoid fatal accidents in an MRI suite will be presented.
