头部运动系统地扭曲临床和研究MRI数据。运动伪影有偏见的结果,从许多结构和功能的大脑MRI研究。去除运动伪影的有效方法是排除受头部运动影响的MRI数据帧。然而,这种事后帧删失可能导致我们的儿科患者队列中50%或更多的数据丢失率。因此,许多扫描仪操作员收集额外的“缓冲数据”,这是一种昂贵的做法,其本身并不能保证为给定的参与者提供足够的高质量MRI数据。因此,我们开发了一个易于设置,易于使用的Framewise集成实时MRI监测(FIRMM)软件套件,为扫描仪操作员提供实时头部运动分析,使他们能够扫描每个受试者,直到收集到所需数量的低运动数据。我们的分析表明,使用FIRMM来确定每个人的理想扫描时间可以减少50%或更多的总脑部MRI扫描时间和相关成本。
Head motion systematically distorts clinical and research MRI data. Motion artifacts have biased findings from many structural and functional brain MRI studies. An effective way to remove motion artifacts is to exclude MRI data frames affected by head motion. However, such post-hoc frame censoring can lead to data loss rates of 50% or more in our pediatric patient cohorts. Hence, many scanner operators collect additional ‘buffer data’, an expensive practice that, by itself, does not guarantee sufficient high-quality MRI data for a given participant. Therefore, we developed an easy-to-setup, easy-to-use Framewise Integrated Real-time MRI Monitoring (FIRMM) software suite that provides scanner operators with head motion analytics in real-time, allowing them to scan each subject until the desired amount of low-movement data has been collected. Our analyses show that using FIRMM to identify the ideal scan time for each person can reduce total brain MRI scan times and associated costs by 50% or more.
