Radio frequency fields used in MR imaging may result in patient heating. This article reviews the physics, physiology, and safety considerations of radio frequency heating of patients during MR examinations. Frequently, monitoring equipment, implants, braces, surface coils, or other devices are introduced into the patient vicinity. A section investigates safety aspects of such devices. Appropriate limits for radio frequency power deposition during MR examinations are explored.
磁共振成像中使用的射频场可能会导致患者发热。本文综述了磁共振检查期间患者射频加热的物理、生理及安全考量。通常，监测设备、植入物、支架、表面线圈或其他装置会被放置在患者附近。有一部分内容研究了此类装置的安全问题。探讨了磁共振检查期间射频功率沉积的适当限值。
