| Summary: | Magnetic resonance imaging (MRI) is a commonly used procedure in the diagnosis and evaluation of diseases. While the relative safety and advantages of MRI over other imaging technologies resulted in its ever increasing use, there are a number of safety issues resulting from patient-related and equipment-related factors. MRI "safe" equipment is identified as having no ferromagnetic parts or radiofrequency interference. MRI "unsafe" equipment is comprised of ferromagnetic materials or those that cause radiofrequency interference. Monitoring of physiological parameters during an MRI examination is necessary for patients who are sedated or anesthetized, critically ill, or have underlying health issues. The Society for Magnetic Resonance Imaging (SMRI) recommends monitoring of patients at least visually or verbally, and using appropriate physiological monitors for high-risk patients or those unable to respond during MRI. In addition, some patients may require mechanical ventilation, which require the same safety considerations as monitoring. A number of guidelines are available to ensure the safety of patients and healthcare professionals working in an MRI unit. However, evidence for clinical effectiveness of equipment used in MRI settings is limited, particularly for ventilators and physiological monitors. The objective of this report is to summarize the available evidence regarding the clinical effectiveness and evidence-based guidelines for magnetic resonance imaging (MRI)-compatible ventilators and physiological monitoring equipment for use during MRI in adult patients requiring ventilation
