Subject	Developmental Neuroscience
Specific subject area	Magnetic Resonance Imaging in Early Childhood; Brain development
Type of data	NIfTI image files (MRI) T1-weighted Imaging Dataset Arterial Spin Labelling (ASL) Dataset Diffusion Tensor Imaging (b = 750 s/mm2) Dataset Passive viewing functional MRI Dataset Accompanying Microsoft Office Excel Spreadsheet
How data were acquired	Magnetic Resonance Imaging Data were acquired using the same General Electric 3T MR750w system and 32-channel head coil (GE, Waukesha, WI) at the Alberta Children's Hospital in Calgary, Canada
Data format	Raw (quality checked)
Parameters for data collection	T1-weighted images were acquired using a FSPGR BRAVO sequence. ASL images were acquired with the vendor supplied (GE) pseudo continuous 3D ASL sequence. Diffusion tensor imaging data were acquired using a single shot spin echo echo-planar imaging sequence. Passive viewing fMRI data were acquired with a gradient-echo echo-planar imaging (EPI) sequence.
Description of data collection	Children were recruited from the local community and an ongoing prospective study (APrON) in Calgary, Canada [4]. All imaging was conducted using the same General Electric 3T MR750w system and a 32-channel head coil (GE, Waukesha, WI) at the Alberta Children's Hospital in Calgary, Canada. Children were scanned without sedation, either while they were awake and watching a movie of their choice, or while they were sleeping.
