Prenatal exposure to methadone is associated with microstructural
alterations in major white matter tracts, assessed by a reduction in fiber-bundle
cross-section and fiber density and cross-section apparent soon after birth.
Figure 1: The top panels show
the areas where the prenatal methadone exposed group has lower FC and the
bottom panels show and the areas where they have lower FDC values. All the
results are overlaid to the WM FOD template for reference. Axial and coronal views
follow radiological convention.
