Diffusion Tensor Imaging (DTI)

Diffusion Tensor Imaging (DTI) is a Magnetic Resonance Imaging‑based neuroimaging technique that makes it possible to estimate the location, orientation, and anisotropy of the white matter tracts of the brain.

In YOUth, the fetal DTI was a DTI b400 with the following parameters: 45 2mm slices; echo time (TE) 117 ms; repetition time (TR) 7533 ms; flip angle 90 degrees; in-plane voxel size 2x2mm^2. The neonatal DTI had a 45 directions sequence with the following parameters: 45 2mm slices; echo time (TE) 80 ms; repetition time (TR) 6500 ms; flip angle 90 degrees; in-plane voxel size 2x2mm^2. The adolescent DTI consisisted of high resolution multi-shell diffusion weighted imaging (DWI) scans with the following parameter settings: 95 different diffusion-weighted directions (15 with b-value 500 s/mm^2, 30 with b- value 1000 s/mm^2, 60 with 2000 s/mm^2 and every 10th scan one diffusion unweighted (b=0) scan); 66 slices; slice thickness = 2 mm (no gap); FOV = 224x224 mm; acquisition matrix = 112x112; SENSE parallel imaging factor = 1.3; multiband factor 3; TR = 3500 ms; TE = 99 ms; no cardiac gating; total acquisition time = 510 s. In addition, two short (20 s each) DWI scans were acquired (one with a reversed k-space readout) to correct for susceptibility artefacts. All files are in classic DICOM format.
