Neonates are grouped according to corrected gestational age at scan time with those aged between two gestational timepoints assigned to the lower time point – e.g. from 37 weeks and 0 days to 37 weeks and 6 days denoted as 37 weeks of gestational age. You can select a diffusion metric (ADC, FA or MD), scroll through the ADC brain map, and view a plot displaying the age-specific diffusion metrics by clicking on each voxel. By hovering your mouse over specific plot points, you can view the mean ± SD for gestational age at scan time. The sample size of neonates contributing to the calculations at each particular gestational age cohort is also displayed.

MRIs performed on a Siemens 3T Skyra scanner.
Axial DWIs: TR=6500 ms, TE=90 ms, Flip angle=90, field of view 22x22 cm, slice thickness 4 mm, matrix of 130x130, and b-values of 0 and 1000 s/mm2.
Axial DTIs were obtained using a single-shot, echoplanar imaging sequence: TR=10200 ms, TE=94 ms, Flip angle=90, field of view 18x18 cm, slice thickness 2.5 mm, matrix of 128x128, a single b-0 and 30 b-1000 s/mm2 acquisition
