This review aimed to summarise the effectiveness of preparation programs for magnetic resonance imaging (MRI) in children using mock scanners and the success rates by systematically reviewing the current literature. We initially identified 67 articles using the search terms "MRI," "mock" and "child" on online databases. All studies involving a preparation programme for MRI on children ages 18 years or younger, healthy children and those with medical diagnoses were included. The authors extracted data on study design, participant data, details of the MRI protocol and the total numbers of patients who underwent preparation programs and were scanned while awake, without sedation or general anesthesia. Twenty-three studies were included in this review. Preparation programs included in-home and hospital/research facility components; these consisted of a mock scanner, explanatory booklets, recorded MRI scan sounds and other educational materials. The success rate of MRI after the preparation programme reported in each study ranged from 40% to 100%. When all participants from studies that specifically assessed the efficacy of preparation programs were combined, participants who underwent a preparation programme (n = 196) were more likely to complete a successful MRI than those who did not undergo a preparation programme (n = 263) (odds ratio [OR] = 1.98). Our results suggest that preparation programs may help reduce the risk of children failing MRI scans.
本综述旨在通过系统回顾当前文献，总结使用模拟扫描仪的儿童磁共振成像（MRI）准备程序的有效性及成功率。我们最初在在线数据库中使用搜索词“MRI”“模拟”和“儿童”识别出67篇文章。纳入所有涉及18岁及以下儿童、健康儿童以及有医学诊断的儿童的MRI准备程序的研究。作者提取了关于研究设计、参与者数据、MRI方案细节以及接受准备程序并在清醒状态下（未使用镇静剂或全身麻醉）进行扫描的患者总数的数据。本综述纳入了23项研究。准备程序包括家庭和医院/研究机构部分；这些包括模拟扫描仪、解释性小册子、录制的MRI扫描声音和其他教育材料。每项研究报告的准备程序后MRI的成功率在40%至100%之间。当将专门评估准备程序疗效的研究中的所有参与者合并时，接受准备程序的参与者（n = 196）比未接受准备程序的参与者（n = 263）更有可能成功完成MRI（优势比[OR]=1.98）。我们的结果表明，准备程序可能有助于降低儿童MRI扫描失败的风险。
