BACKGROUND Pediatric patients are often sedated for magnetic resonance imaging (MRI) scans to ensure images are of diagnostic quality. However, access time for MRIs requiring sedation is often long due to high patient volumes and limited sedation resources. OBJECTIVE This study examined the effectiveness of an MRI Try Without sedation program to decrease the wait time for obtaining an MRI while simultaneously ensuring diagnostic-quality images. MATERIALS AND METHODS A retrospective chart review was performed on subjects who utilized the MRI Try Without program from April 2014 through June 2015 at a dedicated pediatric institution. Child life specialist preparations and access time (i.e. time from exam ordered to exam completed) were recorded in each patient's electronic medical record. MRI images were evaluated for image quality by a pediatric neuroradiologist. RESULTS A total of 134 patients participated in the MRI Try Without program (mean age: 6.9±1.7 years), all of whom received interventions from a child life specialist. The average number of days between when the order was placed and when the MRI was completed using the MRI Try Without program was 15.4±18.5 days, while the third-available appointment for sedation/anesthesia was 46.2 days (standard deviation [SD]±15.7 days). Nearly all patients received a "good" or "very good" image quality determination (87.3%) and only 5 (3.8%) patients were recommended for repeat examination for diagnostic-quality images. CONCLUSION Utilization of an MRI Try Without sedation program, with child life specialist interventions, decreased the wait time for obtaining an MRI while still providing diagnostic-quality images.

MRI Try Without程序对患者访问的影响。

背景技术小儿患者经常被镇静用于磁共振成像（MRI）扫描，以确保图像具有诊断质量。但是，由于患者数量大和镇静资源有限，需要镇静的MRI的访问时间通常很长。目的这项研究检查了MRI Try Without镇静程序的有效性，以减少获得MRI的等待时间，同时确保诊断质量的图像。材料与方法自2014年4月至2015年6月，在专门的儿科机构对使用MRI Try Without程序的受试者进行了回顾性图表审查。儿童生活专家的准备工作和访问时间（即从订购检查到完成检查的时间）记录在每位患者的电子病历中。儿科神经放射科医生对MRI图像的图像质量进行了评估。结果共有134位患者参加了MRI Try Without程序（平均年龄：6.9±1.7岁），所有患者均接受了儿童生命专家的干预。从下订单到使用MRI Try Without程序完成MRI之间的平均天数为15.4±18.5天，而第三次可用的镇静/麻醉任命为46.2天（标准差[SD]±15.7）天）。几乎所有患者都获得了“好”或“非常好”的图像质量测定结果（87.3％），并且仅建议5位（3.8％）患者进行重复检查以获取诊断质量图像。结论利用MRI Try Without镇静程序，并辅以儿童生命专家干预措施，
