![]() change in signal intensity from one voxel to the next), where areas of high. ![]() 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. Pre-surgical structural MRI was acquired in one of two 3 tesla Siemens Skyra. 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. 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. However, such post-hoc frame censoring can lead to data loss rates of 50% or more in our pediatric patient cohorts. An effective way to remove motion artifacts is to exclude MRI data frames affected by head motion. ![]() Motion artifacts have biased findings from many structural and functional brain MRI studies. Head motion systematically distorts clinical and research MRI data. ![]()
