Neuroimaging studies in (pre)adolescent populations have steadily increased in number over the last decade. However, dental braces are common amongst (pre)adolescents and introduce metal-related artifacts in the images. Excluding individuals with braces from epidemiological studies may lead to selection bias and missingness in repeated measures. To this end we configured a T1-weighted 2D FLAIR sequence and compared it to a T1-weighted 3D SPGR sequence. Compared to SPGR, the FLAIR sequence suffered less from metal artifacts and performed similarly in cortical reconstruction and volumetric segmentation. Thus, T1-weighted 2D FLAIR may be a useful alternative for neuroimaging in participants with dental braces.
