To review the epidemiology of anxiety-related reactions during magnetic resonance imaging (MRI) examinations, the feasibility of identifying patients at risk, and the management strategies that have been applied.
Published original articles were retrieved using computerized MEDLINE searches encompassing 1980 through April 1993. Further references were obtained from the primary sources.
All studies obtained through the data search were chosen for review. All data relevant to anxiety-related reactions were analyzed.
Anxiety-related reactions occur in approximately 4% to 30% of patients undergoing MRI, ranging from apprehension to severe reactions that interfere with the performance of the test. Criteria for diagnosis or categorization of the reactions and identification of patients at risk are scanty. Several management strategies have been proposed, including patient education, drug therapy, and cognitive-behavioral intervention.
While a more precise characterization of the nature and incidence of anxiety-related reactions during MRI examinations and better methods of recognizing patients at risk are desirable, a strategy for general and individual prophylaxis, identification of patients at risk, and individual patient management can be developed on the basis of current knowledge.
回顾磁共振成像（MRI）检查期间焦虑相关反应的流行病学、识别高危患者的可行性以及已应用的管理策略。
通过计算机检索MEDLINE获取1980年至1993年4月发表的原始文章。进一步的参考文献从原始资料中获取。
选择通过数据检索获得的所有研究进行综述。分析所有与焦虑相关反应的相关数据。
接受MRI检查的患者中，约4%至30%会出现焦虑相关反应，从忧虑到严重反应不等，严重反应会干扰检查的进行。反应的诊断或分类标准以及高危患者的识别标准很少。已经提出了几种管理策略，包括患者教育、药物治疗和认知行为干预。
虽然希望对MRI检查期间焦虑相关反应的性质和发生率进行更精确的描述，并找到更好的识别高危患者的方法，但基于目前的知识，可以制定出一种针对一般和个体预防、识别高危患者以及个体患者管理的策略。
