51. Artifact Mitigation in Pediatric fMRI: Enhancing Data Quality Through Multi-Echo Data Acquisition and Preprocessing

Functional magnetic resonance imaging (fMRI) has emerged as an important tool for understanding brain development and the neural bases of psychiatric disorders. However, head motion and signal dropout are common challenges, particularly neuroimaging in children and adolescents. Here, we describe a multi-echo fMRI data acquisition and preprocessing pipeline for more robust artifact reduction and quality assurance in pediatric fMRI data. We examine the effects of this pipeline on head motion and signal dropout, as compared to the raw data (prior to preprocessing).
