A dataset for studying the long-term effects of early iron deficiency on brain development in pre-adolescent children

Participants completed a series of structural and functional scans. The structural images were acquired with a T1-weighted magnetization prepared rapid gradient echo sequence: TR (Repetition Time) = 2300 ms, TE (Echo Time) = 2.32 ms, slice thickness = 0.9 mm, voxel size = 0.90 × 0.90 × 0.90 mm3, voxel matrix = 256 × 256, flip angle = 8°, field of view = 240 mm. During the task scan, a total of 546 whole-brain volumes were collected using a T2-weighted gradient echo planar imaging sequence with multi-bands acceleration (TR = 1000 ms, TE = 34 ms, slice thickness = 2.50 mm, voxel size = 2.50 × 2.50 × 2.50 mm3, voxel matrix = 92 × 92, flip angle = 50°, field of view = 230 mm2, slice number = 52, MB-factor = 4).The basic information includes age, sex, head motion, behavioral performance, hematology, and family socioeconomic status.
